TL;DR: In this paper, a new implementation of the Durham semi-analytic model of galaxy formation in which feedback due to active galactic nuclei (AGN) is assumed to quench cooling flows in massive halos is discussed.

TL;DR: In this article, an analytical description of the merging of virialized haloes is presented, which is applicable to any hierarchical model in which structure grows via gravitational instability, and the dependence of the merger rate on halo mass, epoch, the spectrum of initial density fluctuations and the density parameter Ω 0 is explicitly quantified.

TL;DR: In this article, a new implementation of the Durham semi-analytic model in which feedback due to active galactic nuclei (AGN) is assumed to quench cooling flows in massive halos is discussed.

TL;DR: The GALFORM model as discussed by the authors is a semi-analytic model for calculating the formation and evolution of galaxies in hierarchical clustering cosmologies, which employs a new Monte-Carlo algorithm to follow the merging evolution of dark matter halos with arbitrary mass resolution.

TL;DR: DESI as discussed by the authors is a ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-space distortions with a wide-area galaxy and quasar redshift survey.
