Dr. Mikael Granvik


I’m a University Researcher at the Department of Physics at U. Helsinki and a Specialist Research Scientist at the Finnish Geospatial Research Institute since 2014. My main research interests currently are

  1. detection of trailed objects in optical images,

  2. estimating the orbital and size-frequency distribution for near-Earth objects (NEOs),

  3. the detectability of temporarily-captured, natural Earth satellites (AKA minimoons),

  4. development of Markov Chain Monte Carlo methods for orbit computation,

  5. asteroid mass estimation through orbital perturbations in the context of large surveys.

In addition I’ve lately been (or still am!) co-authoring papers on mainbelt comets, the spectrometric analysis of NEO 2005 YU55 (which made a close Earth-fly-by in early Nov 2011), near-Earth asteroids on retrograde orbits, the detectability of interstellar comets, etc.

The observational data for my projects comes from mainly two sources at this moment; CSS and PS1. I’m a member of the science teams for PS1, NEOSSat and LSST as well as of the Gaia Data Processing and Analysis Consortium (Gaia DPAC).
