Dr. Mikael Granvik


I’m a non-tenured planetary scientist at the Department of Physics at U. Helsinki. Currently my main research interests are

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

  2. understanding the mechanism that leads asteroids to disrupt at nontrivial distances from the Sun,

  3. the detectability of temporarily-captured, natural Earth satellites (AKA minimoons) with current (Subaru HSC) and future (LSST) assets,

  4. development of Markov Chain Monte Carlo methods for orbit computation, particularly in the context of Gaia,

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

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).
