TL;DR: In this paper, the authors introduce decorated HODs, a new, exible class of models designed to account for assembly bias, which minimally expand the parameter space and maximize the independence between traditional and novel HOD parameters.

TL;DR: Halotools provides a modular platform for creating mock universes of galaxies starting from a catalog of dark matter halos obtained from a cosmological simulation, enabling complex models to be built from a set of simple, interchangeable components, including those of your own creation.

TL;DR: In this paper, the authors investigate the ability of current implementations of galaxy group finders to recover colour-dependent halo occupation statistics, and they conclude that proper inference of color-dependent statistics from group catalogues is best achieved using forward modelling (i.e. running group finder over mock data) or by implementing a correction scheme based on the HTP, as long as the latter is not too strongly model dependent.

TL;DR: In this article, a detailed study of how dark matter haloes assemble their mass and grow their central potential well is presented, and the authors characterize these via their mass accretion histories (MAHs) and potential well growth histories (PWGHs), which they extract from the Bolshoi simulation and from semi-analytical merger trees supplemented with a method to compute the maximum circular velocity, Vmax, of progenitor haloes.

TL;DR: Korytov et al. as discussed by the authors proposed cosmoDC2, a large synthetic galaxy catalog designed to support precision dark energy science with the Large Synoptic Survey Telescope (LSST).
