The research of the Theoretical Extragalactic group concentrates on trying to understand how galaxies have formed and evolved into the galaxy population that we observe in the present-day Universe. In addition, we study the formation and evolution of supermassive black holes and stellar clusters.
KETJU
We have developed the KETJU code that allows modelling galactic-scale dynamical and astrophysical processes, while simultaneously solving the dynamics of supermassive black holes and surrounding stellar systems at subparsec scales.
SIBELIUS
In the Simulations Beyond the Local Universe (SIBELIUS) project the goal is to simulate the formation of the Milky Way and the Local Group of galaxies using simulations that have been constrained by observations of the local large-scale structure.
Other Projects
Our group has also worked on a variety of other research topics including the formation and evolution of stellar clusters and supermassive black holes. We have also run simulations of both galaxy mergers and galaxies forming in a full cosmological setting.
We also organise the Helsinki Astrophysics Seminar hosting weekly talks during term time on a wide range of topics in astronomy and astrophysics.
