KETJU
The KETJU project funded by the European Research Council (ERC) and the Academy of Finland (AoF) studies the dynamics and impact of supermassive black holes using numerical simulations. The code making these simulations possible is publicly available.
Other research topics of our group members include the formation and evolution of the Local Group of galaxies, the formation and evolution of stellar clusters, the formation of the first supermassive black holes and the formation and evolution of galaxies.

Published Article: RABBITS - I. The crucial role of nuclear star formation in driving the coalescence of supermassive black hole binaries
In this article we systematically study the impact of galaxy formation processes (i.e. gas cooling, star formation, supermassive black hole (SMBH) accretion, stellar, and AGN feedback) on the merger timescale of SMBH binaries in hydrodynamical galaxy merger simulations. We highlight the critical role of nuclear star formation in setting the merger timescale of SMBH binaries for a fixed orbital eccentricity.
Published Article: Chemical evolution of local post-starburst galaxies: implications for the mass-metallicity relation
In this article led by researchers at the University of St. Andrews we study the chemical enrichment and quenching of star formation in a sample of observed post-starburst (PSB) galaxies.
Published Article: Distinct distributions of elliptical and disk galaxies across the Local Supercluster as a ΛCDM prediction
In this article published in Nature Astronomy, we use the SIBELIUS DARK constrained simulation to study the distribution of the brightest ellipticals and the brightest disk galaxies in the Local Universe and show that the distribution of these bright galaxies are in accordance with the predictions of the standard Lambda Cold Dark Matter (ΛCDM) model.
