Accretion of galaxy groups into galaxy clusters

JA Benavides, LV Sales… - Monthly Notices of the …, 2020 - academic.oup.com
We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM.
We select 10 clusters with virial mass M 200∼ 1014 from the cosmological hydrodynamical …

The SLUGGS survey: a comparison of total-mass profiles of early-type galaxies from observations and cosmological simulations, to∼ 4 effective radii

S Bellstedt, DA Forbes, AJ Romanowsky… - Monthly Notices of …, 2018 - academic.oup.com

Formation of S0 galaxies through mergers-Evolution in the Tully-Fisher relation since z~ 1

T Tapia, MC Eliche-Moral, H Aceves… - Astronomy & …, 2017 - aanda.org
Context. Lenticular (S0) galaxies are known to derive from spiral galaxies. The fact that S0s
nearly obey the Tully-Fisher relation (TFR) at z~ 0 (as spirals have done in the last~ 9 Gyr) is …

Forming Lenticular Galaxies via Violent Disk Instability

K Saha, A Cortesi - The Astrophysical Journal Letters, 2018 - iopscience.iop.org
Lenticular galaxies are generally thought to have descended from spirals via morphological
transformation, although recent numerical simulations have shown that minor or even major …

Formation of S0 galaxies through mergers-explaining angular momentum and concentration change from spirals to S0s

M Querejeta, MC Eliche-Moral, T Tapia… - Astronomy & …, 2015 - aanda.org
The CALIFA team has recently found that the stellar angular momentum and concentration
of late-type spiral galaxies are incompatible with those of lenticular galaxies (S0s) …

X-shooter Spectroscopy and HST Imaging of 15 Massive Quiescent Galaxies at z≳ 2

M Stockmann, S Toft, A Gallazzi, S Zibetti… - The Astrophysical …, 2019 - iopscience.iop.org
We present a detailed analysis of a large sample of spectroscopically confirmed massive
quiescent galaxies (MQGs; log (M*/M⊙)∼ 11.5) at z≳ 2. This sample comprises 15 galaxies …

MHD simulations of ram pressure stripping of a disc galaxy

M Ramos-Martínez, GC Gómez… - Monthly Notices of the …, 2018 - academic.oup.com
The removal of the interstellar medium (ISM) of disc galaxies through ram pressure stripping
(RPS) has been extensively studied in numerous simulations. Nevertheless, the role of …

Formation of S0 galaxies through mergers-Antitruncated stellar discs resulting from major mergers

A Borlaff, MC Eliche-Moral, C Rodríguez-Pérez… - Astronomy & …, 2014 - aanda.org
Context. Lenticular galaxies (S0s) are more likely to host antitruncated (Type III) stellar discs
than galaxies of later Hubble types. Major mergers are popularly considered too violent to …

Formation of S0 galaxies through mergers-Bulge-disc structural coupling resulting from major mergers

M Querejeta, MC Eliche-Moral, T Tapia… - Astronomy & …, 2015 - aanda.org
Context. Observations reveal a strong structural coupling between bulge and disc in S0
galaxies, which seems difficult to explain if they have formed from supposedly catastrophic …
