Modeling galaxy formation in a cosmological context presents one of the greatest
challenges in astrophysics today due to the vast range of scales and numerous physical …

Observations of the high-redshift Universe with the 21cm hyperfine line of neutral hydrogen
promise to open an entirely new window onto the early phases of cosmic structure formation …

The transformation of cold neutral intergalactic hydrogen into a highly ionized warm plasma
marks the end of the cosmic dark ages and the beginning of the age of galaxies. The details …

We introduce 21 cmmc: a parallelized, Monte Carlo Markov Chain analysis tool,
incorporating the epoch of reionization (EoR) seminumerical simulation 21 cmfast. 21 cmmc …

Detailed theoretical studies of the high-redshift universe, and especially reionization, are
generally forced to rely on time-consuming N-body codes and/or radiative transfer …

Despite much recent theoretical and observational progress in our knowledge of the early
universe, many fundamental questions remain only partially answered. Here, we review the …

We present a new implementation of radiation hydrodynamics (RHD) in the adaptive mesh
refinement (AMR) code ramses. The multigroup radiative transfer (RT) is performed on the …

ABSTRACT Cosmic Reionization On Computers is a long-term program of numerical
simulations of cosmic reionization. Its goal is to model fully self-consistently (albeit not …

We investigate the observability of cold accretion streams at redshift 3 via Lyα emission and
the feasibility of cold accretion as the main driver of Lyα blobs (LABs). We run cosmological …

We model the escape of ionizing radiation from high-redshift galaxies using high-resolution
adaptive mesh refinement N-body+ hydrodynamics simulations. Our simulations include the …
