1D Kinematics from stars and ionized gas at from the LEGA-C spectroscopic survey of massive galaxies

Rachel Bezanson, Arjen van der Wel, Caroline Straatman +14

We present a comparison of the observed, spatially integrated stellar and ionized gas velocity dispersions of massive () galaxies…

Fast and slow paths to quiescence: ages and sizes of 400 quiescent galaxies from the LEGA-C survey

Po-Feng Wu, Arjen van der Wel, Rachel Bezanson +11

We analyze stellar age indicators (D4000 and EW(H)) and sizes of 467 quiescent galaxies with at drawn from DR2 of the LEGA-C survey.…

The Large Early Galaxy Astrophysics Census (LEGA-C) Data Release II: dynamical and stellar population properties of z ~< 1 galaxies in the COSMOS field

Caroline M. S. Straatman, Arjen van der Wel, Rachel Bezanson +18

We present the second data release of the Large Early Galaxy Astrophysics Census (LEGA-C), an ESO 130-night public spectroscopic survey conducted with VIMOS on the Very Large Teles…

The origin of the mass scales for maximal star formation efficiency and quenching: the critical role of Supernovae

Bruno Henriques, Simon White, Simon Lilly +3

We use the Henriques et al. (2015) version of the Munich galaxy formation model (L-GALAXIES) to investigate why the halo and stellar mass scales above which galaxies are quenched a…

A Lonely Giant: The Sparse Satellite Population of M94 Challenges Galaxy Formation

Adam Smercina, Eric F. Bell, Paul A. Price +5

The dwarf satellites of `giant' Milky Way (MW)-mass galaxies are our primary probes of low-mass dark matter halos. The number and velocities of the satellite galaxies of the MW and…

The Andromeda galaxy's most important merger about 2 billion years ago as M32's likely progenitor

Richard D'Souza, Eric F. Bell

Although the proximity of the Andromeda galaxy (M31) offers an opportunity to understand how mergers affect galaxies, uncertainty remains about M31's most important mergers. Previo…
