Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

We review the physical properties of nearby, relatively luminous galaxies, using results from
newly available massive data sets together with more detailed observations. First, we …

At fixed galaxy stellar mass, there is a clear observational connection between structural
asymmetry and offset from the star-forming main sequence, ΔSFMS. Herein, we use the …

Galactic archaeology based on star counts is instrumental to reconstruct the past mass
assembly of Local Group galaxies. The development of new observing techniques and data …

We develop a general physical model for how galactic disks survive and/or are destroyed in
mergers and interactions. Based on simple dynamical arguments, we show that gas …

We use a suite of semi-empirical models to predict the galaxy–galaxy merger rate and
relative contributions to bulge growth as a function of mass (both halo and stellar), redshift …

There is observational evidence for inside-out growth of giant elliptical galaxies since z≳ 2–
3, which is–in contrast to disc galaxies–not driven by in situ star formation. Many of the∼ …

Associated with one of the most important forms of active galactic nucleus (AGN) feedback,
and showing a strong preference for giant elliptical host galaxies, radio AGN (L_ 1.4\, GHz> …

We investigate the formation of the stellar halos of four simulated disk galaxies using high-
resolution, cosmological SPH+ N-body simulations. These simulations include a self …

We present simulations of the formation of thick discs via the accretion of two-component
satellites onto a pre-existing thin disc. Our goal is to establish the detailed characteristics of …
