How Does Feedback Affect Milky Way Satellite Formation? by Geen, S, Slyz, A, Devriendt, J

“…We use sub-parsec resolution hydrodynamic resimulations of a Milky Way (MW) like galaxy at high redshift to investigate the formation of the MW satellite galaxies. More specifically, we assess the impact of supernova feedback on the dwarf progenitors of these satellite, and the efficiency of a simple instantaneous reionisation scenario in suppressing star formation at the low-mass end of this dwarf distribution. …”

Satellite survival in highly resolved Milky Way class haloes by Geen, S, Slyz, A, Devriendt, J

“… Surprisingly little is known about the origin and evolution of the Milky Way's satellite galaxy companions. UV photoionisation, supernova feedback and interactions with the larger host halo are all thought to play a role in shaping the population of satellites that we observe today, but there is still no consensus as to which of these effects, if any, dominates. …”

Feeding compact bulges and supermassive black holes with low angular-momentum cosmic gas at high redshift by Dubois, Y, Pichon, C, Haehnelt, M, Kimm, T, Slyz, A, Devriendt, J, Pogosyan, D

“…Structures falling in along the filaments (satellite galaxies) or formed by gravitational instabilities triggered by the inflow (star clusters) further reduce the angular momentum of the gas in the bulge. …”
