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. …”

Caught in the rhythm: how satellites settle into a plane around their central galaxy by Welker, C, Dubois, Y, Pichon, C, Devriendt, J, Chisari, N

“…Using the cosmological hydrodynamics simulation Horizon-AGN, we investigate the spatial distribution of satellite galaxies relative to their central counterpart in the redshift range between 0.3 and 0.8. …”

On the filamentary environment of galaxies by Gay, C, Pichon, C, Borgne, D, Teyssier, R, Sousbie, T, Devriendt, J

“…The origin of this bimodality is investigated and seems to follow from the ram pressure stripping of satellite galaxies within the more massive clusters of the simulation. …”

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. …”

Accretion, feedback and galaxy bimodality: a comparison of the GalICS semi-analytic model and cosmological SPH simulations by Cattaneo, A, Blaizot, J, Weinberg, D, Colombi, S, Dave, R, Devriendt, J, Guiderdoni, B, Katz, N, Keres, D

“…Our results imply that the observational failings of the SPH simulation and the no-feedback GalICS model are a consequence of missing input physics rather than computational inaccuracies, that truncating gas accretion by satellite galaxies automatically produces a bimodal galaxy distribution with a red sequence, but that explaining the red colours of the most massive galaxies requires a mechanism like AGN feedback that suppresses the accretion onto central galaxies in large haloes.…”

nIFTy Cosmology: the clustering consistency of galaxy formation models by Pujol, A, Skibba, R, Gaztañaga, E, Benson, A, Blaizot, J, Bower, R, Carretero, J, Castander, F, Cattaneo, A, Cora, S, Croton, D, Cui, W, Cunnama, D, Lucia, G, Devriendt, J, Elahi, P, Font, A, Fontanot, F, Garcia-Bellido, J, Gargiulo, I, Gonzalez-Perez, V, Helly, J, Henriques, B, Hirschmann, M, Knebe, A, Lee, J, Mamon, G, Monaco, P, Onions, J, Padilla, N, Pearce, F, Power, C, Somerville, R, Srisawat, C, Thomas, P, Tollet, E, Vega-Martínez, C, Yi, S

“…We also show that galaxy formation models that do not include orphan satellite galaxies have a significantly lower 2PCF on small scales, consistent with previous studies. …”
