The discovery of a gravitational wave (GW) signal from a binary neutron star (BNS) merger
(Abbott et al. 2017a) and the kilonova emission from its remnant (Coulter et al. 2017; Abbott …

Progress in observational cosmology over the past five years has established that the
Universe is dominated dynamically by dark matter and dark energy. Both these new and …

Gravitational-wave detections provide a novel way to determine the Hubble constant,–,
which is the current rate of expansion of the Universe. This 'standard siren'method, with the …

We present a new version of the galform semi-analytical model of galaxy formation. This
brings together several previous developments of galform into a single unified model …

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 …

The extragalactic background light (EBL) is of fundamental importance both for
understanding the entire process of galaxy evolution and for γ-ray astronomy, but the overall …

We simulate the growth of galaxies and their central supermassive black holes by
implementing a suite of semi-analytic models on the output of the Millennium Run, a very …

Recent observations of the distant Universe suggest that much of the stellar mass of bright
galaxies was already in place at z> 1. This presents a challenge for models of galaxy …

We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS),
employing a direct Fourier method. The sample used comprises 221 414 galaxies with …

We report the final redshift release of the 6dF Galaxy Survey (6dFGS), a combined redshift
and peculiar velocity survey over the southern sky (| b|> 10°). Its 136 304 spectra have …
