The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

Quasars at cosmic dawn provide powerful probes of the formation and growth of the earliest
supermassive black holes (SMBHs) in the Universe, their connections to galaxy and …

Modern Cosmology, Third Edition provides a detailed introduction to the field of cosmology.
Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaître …

We describe the GALFORM semi-analytic model for calculating the formation and evolution
of galaxies in hierarchical clustering cosmologies. It improves upon, and extends, the earlier …

The rapidly expanding field of galaxy formation lies at the interface between astronomy,
particle physics, and cosmology. Covering diverse topics from these disciplines, all of which …

We present updated constraints on the free-streaming of warm dark matter (WDM) particles
derived from an analysis of the Lyman-α flux power spectrum measured from high-resolution …

We present an estimate of the global budget of baryons in all states, with conservative
estimates of the uncertainties, based on all relevant information we have been able to …

We present moderate-resolution Keck spectroscopy of quasars at z= 5.82, 5.99, and 6.28,
discovered by the Sloan Digital Sky Survey (SDSS). We find that the Ly α absorption in the …

The presence of dust in galaxies removes one‐half or more of the stellar energy from the UV‐
optical budget of the universe and has a profound impact on our understanding of how …

ABSTRACT Approximately 30%–40% of all baryons in the present-day universe reside in a
warm-hot intergalactic medium (WHIM), with temperatures in the range 10 5< T< 10 7 K. This …
