We summarize what large surveys of the contemporary Universe have taught us about the
physics and phenomenology of the processes that link the formation and evolution of …

The most successful cosmological models to date envision structure formation as a
hierarchical process in which gravity is constantly drawing lumps of matter together to form …

Recent observational and theoretical breakthroughs make this an exciting time to be
working towards understanding the physics of galaxy formation. The goal of this review is to …

We investigate the origin of galaxy bimodality by quantifying the relative role of intrinsic and
environmental drivers to the cessation (or 'quenching') of star formation in over half a million …

Galaxy groups are more than an intermediate scale between clusters and halos hosting
individual galaxies, they are crucial laboratories capable of testing a range of astrophysics …

We present the first results from romulusc, the highest resolution cosmological
hydrodynamic simulation of a galaxy cluster run to date. romulusc, a zoom-in simulation of a …

The thermodynamics of the diffuse, X-ray emitting gas in clusters of galaxies is determined
by gravitational processes associated with shock heating, adiabatic compression, and non …

The prevalence of radio-loud active galactic nucleus (AGN) activity in present-day massive
haloes is determined using a sample of 625 nearby groups and clusters selected from the …

We use gigaparticle N-body simulations to study galaxy cluster populations in Hubble
volumes of Λ CDM (Ω m= 0.3, Ω Λ= 0.7) and τ CDM (Ω m= 1) world models. Mapping past …

We consider several mechanisms that possibly affect the evolution of disk galaxies in
clusters using analytical models based on a hierarchical clustering scenario. We especially …
