Space Physics

Understanding the influence of active regions on coronal hole open magnetic flux

Coronal holes (CHs) are considered as the primary source of open magnetic flux emanating from the Sun and filling up the interplanetary space. They are observed in Extreme UltraViolet (EUV) wavelengths as dark patches on the solar disc and in white-light corona observations as less bright areas due to their lower density. CHs are often considered as areas with potential magnetic field structure, meaning they are free of currents and evolving very slowly with time. Contrary, Active Regions (ARs) are characterized by non-potential and rapidly evolving magnetic fields. When ARs are present at the boundaries of CHs they can affect the CH structure, via reconnection, and therefore they impact the open flux associated with that CH. A current topic of investigation is to understand the extent of this and how it affects the interplanetary magnetic field. During the summer internship the candidate will build a database of CH-AR pairs and study the possible impacts the AR (and AR emergence) had on the CH characteristics and open flux. This will be done via analysing observations and if time allows via simulations. 

The research is part of the SOFTCAT project funded by the Research Council of Finland (Academy Research Fellow grant No 355659). 

The project is suitable for BSc and MSc thesis. 

For more details please contact the PI of the project Dr. Eleanna Asvestari (eleanna.asvestari@helsinki.fi)

The summer work positions offered by the Vlasiator team at the Space Physics group 

More information about the group: https://www.helsinki.fi/en/researchgroups/vlasiator . We are looking for applicants who will write a Bachelor’s/Master’s thesis on the topic of the summer work. Please indicate in your application which project you are most interested in.

Hybrid-Vlasov simulations of space plasma turbulence 

The solar system is filled with plasmas that display a rich array of physical phenomena, one of which is turbulence.  Turbulence is a chaotic process that plays a fundamental role in transferring energy from large to small scales (i.e. from fluid to ion and electron scales) in space plasmas.   

The space physics group at Helsinki maintains the Vlasiator code, which produces one of the most advanced simulations of the Earth’s plasma environment. In this project, you will use the Vlasiator code to generate turbulent behaviour in the simulated plasma.  The successful candidate will play a leading role in developing this new modelling capability for the research group. 

Applicants should have some familiarity with Linux, Bash and/or high-performance computing (HPC) environments, and experience with programming in general. Vlasiator is written in C++, so existing C++ programming skills are beneficial, but this can also be learnt during the project.  Some familiarity with plasma physics would be beneficial but not essential. 

The work performed will be suitable for either a BSc or MSc thesis, and funding is available for 3 months during summer 2025.   

Supervisors: Simon Good, simon.good@helsinki.fi, Jonas Suni, jonas.suni@helsinki.fi 

Vlasiator Timeclasses development & optimization 

Kinetic plasma simulations of the geospace require resolving very disparate spatiotemporal scales. For example, the Earth magnetic dipole dictates a timescale to be resolved (ion gryofrequency) and the steep increase in magnetic field magnitude drives the simulation timestep down fast. Global simulations with locally varying timesteps (timeclasses) are required to reach the inner portions of the Earth's magnetosphere. 

In Vlasiator's high-performance computing context, this leads to nontrivial load-balancing. The task of this summer internship is to test and optimize load balancing for timeclass-enabled Vlasiator simulations. Prerequisites include knowledge of C++ and tool of high-perfomance computing (MPI). Contact: Markku Alho (markku.alho@helsinki.fi)

Particle acceleration associated with foreshock transients 

When solar wind particles are reflected at Earth's bow shock, they create a dynamic region known as the foreshock. In this region, backstreaming particles interact with incoming solar wind discontinuities, leading to the formation of various foreshock transients. These transients play a crucial role in accelerating and energizing plasma and could have a global effect on the near-Earth plasma environment. This project focuses on studying specific foreshock transients, such as foreshock bubbles and hot flow anomalies, and how they contribute to plasma energization. The investigation could utilize data from NASA’s Magnetospheric MultiScale (MMS) mission as well as global hybrid-Vlasov simulations with Vlasiator. By combining observational and simulation-based approaches, this project aims to enhance our understanding of how these transients influence space plasma dynamics. The data analysis will be done using Python. Contact: Souhail Dahani (souhail.dahani@helsinki.fi) and Lucile Turc (lucile.turc@helsinki.fi). 

Theoretical Extragalactic astrophysics

We are looking for summer trainees with an interest in theoretical astrophysics and/or theoretical physics. In addition to theoretical work, our projects include a significant computational aspect. We encourage students interested in theoretical astrophysics and computation to join the Theoretical Extragalactic astrophysics research group for a three-month period over the summer. This year, the projects on offer are related to the KETJU and SIBELIUS projects, which are funded by the 

European Research Council and the Research Council of Finland. KETJU is a simulation code developed to model the dynamics of supermassive black holes in galaxy mergers. Using KETJU the large-scale structure of galaxies can be studied, while simultaneously resolving accurately, the small-scale dynamics close to the supermassive black holes. SIBELIUS employs novel constrained simulations to accurately reproduce the Local Universe and test models of cosmology and galaxy formation.

1) Black hole accretion and feedback in merging galaxies

Supermassive black holes (SMBH) at the centre of massive galaxies accrete gas, efficiently converting the potential and kinetic energy of this gas into radiation, which heats the surrounding gas and affects the evolution of the entire galaxy. This interplay between gas and SMBHs is called the black hole accretion and feedback process, which is a key ingredient in modern galaxy formation models. In this project the goal is to use KETJU numerical simulations to study how the accretion and feedback process of binary SMBHs affects the properties of merging galaxies. Good computing skills and knowledge of galaxy formation theory are advantageous for this project.

2) Gravitational wave kicks from merging supermassive black holes

In the final stages of the merger of a supermassive black hole (SMBH) binary, copious amounts of gravitational waves will be emitted. In addition, the merged SMBHs will receive a kick that depends on the orbital orientation, masses and spins of the individual SMBHs prior to the merger. Using the post-Newtonian formalism in KETJU, the gravitational wave energy spectrum as a function of frequency, as well as the amplitude and direction of this kick, can be calculated. In this project the aim is to study the dynamics of merged SMBHs in the centres of massive galaxies. Good computing skills and prior knowledge of general relativity and galactic dynamics are advantageous for this project.

3) The possible origin of the Local Group

We will draw present-day analogues of the Local Group from the UCHUU simulation, one of the world's largest cosmological simulation, and trace them back through cosmic time to explore possible formation scenarios, identify key scenarios, and study the likelihood of various events, including major mergers in the history of the Milky Way or Andromeda, possible past interactions between them, or the exchange of satellite galaxies. Good computing skills (especially python) are advantageous for this project. Related works from the group: Sawala, Teeriaho & Johansson, MNRAS 2023; Sawala et al., MNRAS Letters 2023.

4) Discovering galaxy clusters using constrained simulations

We use an ensemble of constrained simulations of the Local Universe to search for galaxy clusters hiding in the "zone of avoidance". Obscured by the disk of the Milky Way, the zone of avoidance cannot be observed using optical telescopes. However, the SIBELIUS constrained simulations predict the most likely structures that form in this region, given the observed distribution of structures outside of it. In this project, we will use an ensemble of constrained simulation to identify persistent structures within the zone of avoidance and perhaps discover previously unknown galaxy clusters that exist in the real universe. Good statistics and computing skills (especially python) are advantageous for this project. Related works from this group: McAlpine et al., MNRAS, 2022; Sawala et al., Nat. Astron., 2023.

5) Investigating periodic boundary conditions in cosmological simulations

The aim of this project is to modify the StePS simulation code to implement one-directional periodic boundaries, enabling the simulation of universes with cylindrical symmetry. This approach allows for the study of cosmic structures in a way that is not possible with traditional cubic or StePS geometries. Additionally, the project will involve integrating alternative periodic geometries, such as the Poincaré dodecahedral and hexagonal prism geometries, into the StePS code. The student will help implement these geometries and investigate the effects of these boundary conditions on cosmic structure formation. Proficiency in high-performance computing (Python, C/C++, MPI, CUDA) and a solid understanding of cosmology and computational methods are beneficial for this project.

When applying, please indicate your preference for the research topic. All research topics could also form the basis for either a Bachelor or a Master thesis in astrophysics, theoretical physics or a related field. Preference will be given to students, who are working on their Master thesis. For advanced students, there is also a possibility to continue with a PhD thesis project after the successful completion of the Master thesis.

Planetary-System Research

Planetary-system research (PSR) at the University of Helsinki comprises theoretical, computational, experimental, and observational research of Solar System objects, such as asteroids, comets, planets, and planetary satellites. The PSR research has close connections to geophysics, geology, space physics, as well as meteorology and is focused on asteroids (e.g., ESA Gaia mission, ESA Euclid mission, ESA Hera mission in planetary defence to mitigate near-Earth-object collision threat), comets (ESA Comet Interceptor mission),  Mercury (ESA/JAXA BepiColombo and NASA MESSENGER missions), and other atmosphereless bodies, as well as the planet Earth (notably NASA DSCOVR mission).

Astronomical observations are carried out, for example, at the Nordic Optical Telescope (NOT) and, in the future, with the Large Synoptic Survey Telescope (LSST). Ongoing observational and computational multiwavelength analyses also include radar studies of small bodies, the Moon, and Mercury, which provides an additional source of information about their composition and other physical properties in addition to the optical data.

The PSR group runs the Astrophysical Scattering Laboratory consisting of a state-of-the-art levitator-driven scatterometer, UV-Vis-NIR spectrometer, and a polarimetric spectrogoniometer. The development of a backscatterometer based on hyperspectral imaging is ongoing. Laboratory and computational collaboration in X-ray fluorescence spectroscopy progresses with the University of Leicester. The research involves forward and inverse light scattering, X-ray fluorescence, and celestial mechanics methods for accrueing knowledge on individual planetary-system objects as well as entire populations of asteroids and comets.

Within PSR, one-to-two summer trainee positions are opened in the topic of photometric simulations and visualizations with Blender and Python of comets and asteroids, with a link to ESA Comet Interceptor mission.

Computational Plasma Astrophysics Research

Plasma astrophysics is a new, emerging research field aiming to understand the dynamics of astrophysical plasmas – hot ionized gases – from first principles. The Computational Plasma Astrophysics research group at the University of Helsinki uses theoretical and computational methods to study the most extreme plasma environments around neutron stars and black holes. As part of our research, we also specialize in high-performance computing solutions and open-source simulation software. To perform our numerical studies, we maintain our own computational "laboratory" with a dedicated in-house, ~2000-core HILE cluster. We use the cluster to develop the open-source plasma simulation framework Runko. The research group is funded by the European Research Council (ERC) Starting Grant project ILLUMINATOR.

We are looking for ambitious summer trainees interested in studying extreme plasma phenomena with analytical and computational methods. The projects are 1-3 months long with flexible starting dates. The projects can form a basis for a Bachelor’s or Master’s thesis. Available topics include, for example:

1) Plasma simulations of magnetically dominated turbulence. The student will learn how to use the Runko particle-in-cell code to simulate the non-linear dynamics of plasma turbulence. Understanding the dynamics of magnetized turbulence is important for interpreting the observations of accreting black holes.

2) Analysis of strong electromagnetic waves in plasmas. The student will perform theoretical analysis of nonlinear plasma waves and how they interact with the background medium. Strong-wave dynamics are important for understanding the physics of fast radio bursts.

3) Numerical magnetic reconnection simulations. The student will study the relativistic reconnection with plasma simulations and measure the electromagnetic emission from the reconnection layer. Low-frequency emission from reconnection is an interesting new fast radio burst mechanism.

Completion of plasma physics courses is helpful, although not required. Good computational skills and previous experience with Python and/or C++ are advantageous. For more information on our group and other possible research topics, see https://natj.github.io/group

Building a Web Front for LogDelta

Job purpose

The purpose of this job is to enhance [LogDelta] (https://github.com/EvoTestOps/LogDelta), a log analysis tool, by building a web-based front end. Currently, LogDelta operates as a Python program that uses a configuration file to determine its behavior. It takes a set of input logs and, based on the configurations, produces output in two formats:

  • Spreadsheets: Generated in either Excel or CSV format.
  • HTML Visualizations: For more interactive exploration.

Current workflow

The existing workflow involves manually editing configuration files and running the Python program to generate results. While several example configurations are provided, this process may be cumbersome for users unfamiliar with the tool’s configuration options. 

Job goal

The goal of this job is to simplify LogDelta’s usability by creating a user-friendly web interface. With this interface, users can interact with LogDelta through their browser—selecting options and generating results by pressing buttons, rather than editing configuration files manually.  

Development requirements

The current version of LogDelta is distributed as an installable [pip package] (https://pypi.org/project/logdelta/). To achieve the project goal, the following steps are needed:

  1. Web Backend: Run the existing LogDelta implementation as a web service.  
  2. Web Front End: Develop an intuitive interface to tie everything together, making it easy for users to interact with the tool.  

Video description of current LogDelta implementation in [YouTube] (https://www.youtube.com/playlist?list=PLTUjKYPvVhe6JhHBlkJN_yPhVDR5w2ej2). Another point of reference can be [LogAi] (https://github.com/salesforce/logai) tool that was created by SalesForce but unfortunately the package is no longer maintained.

  • Forskningsgrupp: Empirical Software Engineering
  • Handledare/kontaktperson: Mika Mäntylä (mika.mantyla@helsinki.fi)
  • Målgrupp: Sommarjobbet passar för både kandidat- och magisterstuderande.
  • Tillämplighet av ämnet som magisteravhandling:  Ämnet kan även utökas till en magisteravhandling.
Edge Intelligence: Deploying NLP and CV on Embedded Devices

AI is transforming sciences and industries, with use cases spanning Predictive Modeling, Computer Vision (CV), and Natural Language Processing (NLP). While AI applications typically rely on cloud infrastructure and powerful GPUs, this project focuses on deploying AI algorithms on resource-constrained embedded devices such as ESP32, Raspberry Pi, Nvidia Jetson Nano, and Vision AI DevKit. 

The project explores real-time applications, including digital twinning, vehicle counting, and voice-based sentiment analysis. AI models may be trained in the Microsoft Azure Cloud and deployed to edge devices, ensuring efficient and localized processing. For example, our newly funded project aims at generating real-time dynamic air quality information. Thus, we plan to equip a mobile robot with comprehensive air quality sensors and a camera to navigate construction sites. The camera will capture images and videos to facilitate real-time vehicle counting. Computer vision algorithms will be deployed on an edge device to process the footage and count vehicles on-site. The vehicle count data will complement measurements from aerosol and gas sensors, enhancing the accuracy and depth of air quality assessments. 

This position is ideal for a current Master's student, offering the potential to evolve into a thesis project. Future directions could involve testing AI models across diverse edge hardware and refining more advanced algorithms. 

Engineering of Large Foundational Models (flera positioner)

We are looking for multiple interns to work on tools and techniques for the efficient integration and operations of Large Foundation or Language Models (LFM/LLM) and Generative AI in industrial systems. An LFM integration introduces a wide array of risks and challenges due to costs, compliance issues and technical complexities. Our work focuses on leveraging existing LFMs rather than creating new ones, and emphasizing systematic engineering practices in LFM integration, enabling organizations to navigate legal, security, and ethical concerns while aligning with European regulations. Key areas of focus are continuous integration and deployment methodologies tailored to AI systems (such as MLOps, LLMOps, and GenAIOps), including adapting (e.g., fine-tuning, prompting, RAG), testing, monitoring, and life-cycle support.

The work involves implementing research prototypes to explore new ideas and conducting measurements. We can adapt the scope and focus of the work to align with the applicant's skills and interests. Applicants should have strong coding skills, though there are no strict requirements regarding their current stage of studies. Experience in machine learning and software engineering is beneficial. The internships may also be extended beyond the summer, offering opportunities to continue as an MSc thesis worker or part-time research assistant.

The work is part of the industry-driven international research project ELFMo (https://itea4.org/project/elfmo.html), which builds on and extends our earlier projects, including IML4E, IVVES, VesselAI, and AIGA. For more details on these projects, visit https://researchportal.helsinki.fi/en/persons/jukka-k-nurminen/projects/.

Enhanced Middleware for Quantum Software (EM4QS; möjligtvis flera positioner)

We are looking for interns interested in implementation of quantum algorithms and use cases. The work is part of our EM4QS project, which aims to develop enhanced functionality for quantum software stack. Because quantum hardware and its sensitivity to noise limits the size and length of quantum programs, it is important come up with efficient ways to take advantage of the capabilities of quantum hardware. This requires cooperation of all layers in the quantum stack. One of our main interests is efficient compilation infrastructure for quantum programs. 

The work involves implementing test code, analyzing and extrapolating the performance of different solutions, and documenting the results in scientific papers.  Applicants are expected to know the basics of quantum computing. Knowledge of graph theory, linear algebra, and classical compilers, like LLVM,  is a plus. The internships can be extended after summer as MSc thesis worker or part-time research assistant positions.

Graph Algorithms for Bioinformatics

Graphs are ubiquitous models in many application domains, including Bioinformatics. In the Graph Algorithms Team of the wider Algorithmic Bioinformatics group, we can offer a topic on graph algorithms for sequencing data used in RNA transcript discovery.
