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.

SIBELIUS

The SIBELIUS project funded by the Academy of Finland (AoF) studies the formation and evolution of the Local Group of galaxies in their true cosmic environment by utilising constrained numerical simulations.

Published Article: The difficult path to coalescence: massive black hole dynamics in merging low-mass dark matter haloes and galaxies

In this article we systematically study the dynamical sinking of massive black holes in low mass galaxies using the KETJU code. Our idealized high-resolution study highlights the difficulty to bring in and keep low-mass MBHs in the centres of low-mass haloes/galaxies.
