The Formation History of Subhalos and the Evolution of Satellite Galaxies by Shi, Jingjing, Wang, Huiyuan, Mo, Houjun, Vogelsberger, Mark, Ho, Luis C, Du, Min, Nelson, Dylan, Pillepich, Annalisa, Hernquist, Lars

“…We use a scaled formation time (anf) to characterize the mass assembly histories of the subhalos before they are accreted by massive host halos. We find that satellite galaxies in young subhalos ((lownf) are less massive and more gas-rich and have stronger star formation and a higher fraction of ex situ stellar mass than satellites in old subhalos (high anf). …”

“…We examine the red fraction of central and satellite galaxies in the large zCOSMOS group catalog out to z ~ 0.8 correcting for both the incompleteness in stellar mass and for the less than perfect purities of the central and satellite samples. …”

“…These signals lend support to environmentally driven processes that quench satellite galaxies, although variations in the merger histories of central and satellite galaxies also emerge as a viable explanation.…”

Powell, Yves Revaz, Ikkoh Shimizu, Héctor Velázquez, Daniel Ceverino, Joel R. Primack, Thomas R. Quinn, Clayton Strawn, Tom Abel, Avishai Dekel, Bili Dong, Boon Kiat Oh, Romain Teyssier, The AGORA Collaboration

“…When we consider only the halos containing stellar particles at z ∼ 2, the number of satellite galaxies is significantly fewer than that of dark matter halos in all participating AGORA simulations and is comparable to the number of present-day satellites near the Milky Way or M31. …”

Kinematics in galactic tidal tails - A source for Hypervelocity stars? by Piffl, T, Williams, M, Steinmetz, M

“…We use a suite of N-body simulations following the encounter of a satellite galaxy with its Milky Way-type host galaxy to gather statistics on the properties of stripped-off stars. …”

Active galactic nuclei and the minor merger hypothesis by Kendall, P, Magorrian, J, Pringle, J

“…We find that for a satellite galaxy to be able to merge directly with the nucleus of the host galaxy (for example, to give rise to the compact dust discs which are seen in early-type active galaxies), the initial orbit of the satellite is required to be well aimed. …”

Toward Accurate Modeling of Galaxy Clustering on Small Scales: Halo Model Extensions and Lingering Tension by Gillian D. Beltz-Mohrmann, Adam O. Szewciw, Andreas A. Berlind, Manodeep Sinha

Disassembling the Galaxy with angle-action coordinates by Mcmillan, P, Binney, J

Machine Learning the Dark Matter Halo Mass of Milky Way-Like Systems by Elaheh Hayati, Peter Behroozi, Ekta Patel

“…This method uses only observable information including satellite orbits, distances to nearby larger halos, and the maximum circular velocity of the largest satellite galaxy. In this paper, we demonstrate a proof-of-concept method on simulated dark matter halos; in future papers in this series, we will apply neural networks to estimate the masses of the Milky Way's and M31's dark matter halos, and we will train variations of these networks to estimate other halo properties including concentration, assembly history, and spin axis.…”

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. …”
