Infall of galaxies in groups facilitate mergers within clusters

With grad student Jose Benavides (IATE, Argentina) we looked into mergers happening in and around clusters using the Illustris simulations. These events might be connected to the formation of lenticular galaxies and compact dwarfs.

Formation of Ultra-diffuse galaxies in clusters

Using galaxy clusters from the TNG100 cosmological simulations we find that ultra-diffuse galaxies (UDGs) in clusters can have a dual origin: born-UDGs and tidal-UDGs, the latter formed by tidal disruption of more massive normal galaxies.
