TL;DR: In this paper, the dependence of dark matter halo clustering on halo formation time, density profile concentration, and subhalo occupation number was investigated using high-resolution numerical simulations of a LCDM cosmology.

TL;DR: In this paper, the authors explore the multiphase structure of the circumgalactic medium probed by synthetic spectra through a cosmological zoom-in galaxy formation simulation, and employ a Bayesian method for modelling a combination of absorption lines to derive physical properties of absorbers with a formal treatment of detections, including saturated systems, and non-detections in a uniform manner.

TL;DR: In this article, the evolution of the galaxy cluster mass functions at z=0.05 and z=~0.5 using high-quality Chandra observations of samples derived from the ROSAT PSPC All-Sky and 400deg^2 surveys is discussed.

TL;DR: In this article, the authors conduct a series of high-resolution, dissipationless N-body simulations to investigate the cumulative effect of substructure mergers onto thin disk galaxies in the context of the LCDM paradigm of structure formation.

TL;DR: In this paper, the authors present a model that explains why galaxies form stars on a time scale significantly longer than the time scales of processes governing the evolution of interstellar gas, showing that gas evolves from a non-star-forming to a star-forming state on a relatively short time scale and thus the rate of this evolution does not limit the star formation rate.
