TL;DR: In this paper, the authors present a comprehensive overview of galaxy bias, that is, the statistical relation between the distribution of galaxies and matter, which forms the basis of the rigorous perturbative description of galaxy clustering, under the assumptions of General Relativity and Gaussian, adiabatic initial conditions.

TL;DR: In this article, the observed galaxy power spectrum depends strongly on which gauge is assumed to relate the intrinsic fluctuations in galaxy density to matter perturbations through a linear bias relation, and it reduces to linear bias relations in a synchronous-comoving gauge, corroborating an assumption made in several recent papers.

TL;DR: In this article, the authors studied the escape of Lyα photons from Lyα emitting galaxies (LAEs) and the overall galaxy population using a sample of 99 LAEs at 1.9 (3-6) × 1042 erg s−1 (0.25-0.5 L*), implying an attenuation of ~70% in the UV.

TL;DR: In this article, the authors compare the nonlinear matter power spectrum in real space calculated analytically from third-order perturbation theory with N-body simulations at 1 1, and find that the shape of oscillations is distorted from the linear theory prediction.
