We review the progress in modeling the galaxy population in hydrodynamical simulations of
the ΛCDM cosmogony. State-of-the-art simulations now broadly reproduce the observed …

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting
views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and …

Abstract We introduce the Virgo Consortium's Evolution and Assembly of GaLaxies and their
Environments (EAGLE) project, a suite of hydrodynamical simulations that follow the …

Abstract The Widefield ASKAP L-band Legacy All-sky Blind surveY (wallaby) is a next-
generation survey of neutral hydrogen (H i) in the Local Universe. It uses the widefield, high …

We analyze the physical conditions of the cool, photoionized (T∼ 10 4 K) circumgalactic
medium (CGM) using the COS-Halos suite of gas column density measurements for 44 …

We present an updated version of the so-called Madau model for attenuation of the radiation
from distant objects by intergalactic neutral hydrogen. First, we derive the distribution …

Cosmological simulations of galaxy formation appear to show a" two-phase" character with a
rapid early phase at z≳ 2 during which" in situ" stars are formed within the galaxy from …

We present a model for star formation and supernova feedback that describes the
multiphase structure of star-forming gas on scales that are typically not resolved in …

We examine the temperature history of gas accreted by forming galaxies in smoothed
particle hydrodynamics simulations. About half of the gas follows the track expected in the …

Although galaxies, groups, and clusters contain∼ 10% of the baryons, many more reside in
the photoionized and shocked-heated intergalactic medium (IGM) and in the circumgalactic …
