Numerical effects on the stripping of dark matter and stars in IllustrisTNG galaxy groups and clusters
Mark R. Lovell, Annalisa Pillepich, Christoph Engler +4
The stellar haloes and intra-cluster light around galaxies are crucial test beds for dark matter (DM) physics and galaxy formation models. We consider the role that the numerical r…
Milky Way and Andromeda analogs from the TNG50 simulation
Annalisa Pillepich, Diego Sotillo-Ramos, Rahul Ramesh +7
We present the properties of Milky Way- and Andromeda-like (MW/M31-like) galaxies simulated within TNG50, the highest-resolution run of the IllustrisTNG suite of CDM magneto-hyd…
Satellites of Milky Way- and M31-like galaxies with TNG50: quenched fractions, gas content, and star formation histories
Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi +3
We analyse the quenched fractions, gas content, and star formation histories of ~1200 satellite galaxies with around 198 Milky Way- (MW) and…
The abundance of satellites around Milky Way- and M31-like galaxies with the TNG50 simulation: a matter of diversity
Christoph Engler, Annalisa Pillepich, Anna Pasquali +9
We study the abundance of satellite galaxies around 198 Milky Way- (MW) and M31-like hosts in TNG50, the final instalment in the IllustrisTNG suite of cosmological magnetohydrodyna…
The Stellar Mass Assembly of Low Redshift, Massive, Central Galaxies in SDSS and the TNG300 simulation
Thomas M. Jackson, A. Pasquali, C. Pacifici +3
The stellar mass assembly of galaxies can be affected by both secular and environmental processes. In this study, for the first time, we investigate the stellar mass assembly of $\…
The distinct stellar-to-halo mass relations of satellite and central galaxies: insights from the IllustrisTNG simulations
Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi +9
We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodyn…
The Active Assembly of the Virgo Cluster: Indications for Recent Group Infall From Early-Type Dwarf Galaxies
Thorsten Lisker, Rukmani Vijayaraghavan, Joachim Janz +3
Virgo is a dynamically young galaxy cluster with substructure in its spatial and kinematic distribution. Here, we simultaneously study the phase-space distribution and the main cha…
On the scatter of the present-day stellar metallicity-mass relation of cluster dwarf galaxies
Christoph Engler, Thorsten Lisker, Annalisa Pillepich
We examine the scatter of the relation between stellar mass and stellar metallicity for cluster dwarf galaxies in the cosmological simulation Illustris. The mass-metallicity relati…
