TL;DR: In this paper, the authors present results from a large volume simulation of hydrogen reionization, which combines 3D radiative transfer calculations and an N-body simulation, describing structure formation in the intergalactic medium to detail the growth of H II regions around high-redshift galaxies.

TL;DR: In this paper, the authors investigate the implications of the intergalactic opacity for the evolution of the cosmic UV luminosity density and its sources and show that star-forming galaxies likely dominate the photoionization rate at ≈ 3.

TL;DR: In this paper, the authors present cosmological parameter measurements from the publicly available Baryon Oscillation Spectroscopic Survey (BOSS) data on anisotropic galaxy clustering in Fourier space, using a complete perturbation theory model that properly takes into account the nonlinear effects of dark matter clustering, short-scale physics, galaxy bias, redshift space distortions, and large-scale bulk flows.

TL;DR: In this article, the authors measured the evolution of the intergalactic Lyα effective optical depth over the redshift range of 2 ≤ z≤ 4.2 from a sample of 86 high-resolution, high-S/N quasar spectra obtained with the ESI and HIRES spectrographs on Keck and with the MIKE Spectrograph on Magellan.

TL;DR: The COmoving Lagrangian Acceleration (COLA) method as mentioned in this paper is an N-body method for solving for large scale structure (LSS) in a frame that is comoving with observers following trajectories calculated in LPT.
