Cosmological radiative transfer codes comparison project – I. The static density field tests
Radiative transfer (RT) simulations are now at the forefront of numerical astrophysics. They are becoming crucial for an increasing number of astrophysical and cosmological problems; at the same time
Simulating Cosmic Reionization at Large Scales I: the Geometry of Reionization
We present the first large-scale radiative transfer simulat ions of cosmic reionization, in a simulation volume of (100 h 1 Mpc) 3 . This is more than a 2 orders of magnitude improvement over
The halo mass function through the cosmic ages
In this paper we investigate how the halo mass function evolves with redshift, based on a suite of very large (with N_p = 3072^3 - 6000^3 particles) cosmological N-body simulations. Our halo
Self-regulated reionization
Recently, we have presented the first, truly large-scale radiative transfer simulations of inhomogeneous cosmic reionization which resolve all the possible halo sources down to the dwarf galaxy mass
Upper limits on the 21 cm Epoch of Reionization power spectrum from one night with LOFAR
We present the first limits on the Epoch of Reionization 21 cm H I power spectra, in the redshift range z = 7.9–10.6, using the Low-Frequency Array (LOFAR) High-Band Antenna (HBA). In total, 13.0 hr
On the use of Lyα emitters as probes of reionization
We use numerical simulations to study the effects of the patchiness of a partly reionized intergalactic medium (IGM) on the observability of Lyα emitters (LAEs) at high redshifts (z ≳ 6). We present
Simulating cosmic reionization at large scales – II. The 21-cm emission features and statistical signals
We present detailed predictions for the redshifted 21-cm signal from the epoch of reionization. These predictions are obtained from radiative transfer calculations on the results of large-scale (100
The Inhomogeneous Background Of H2-Dissociating Radiation During Cosmic Reionization
The first, self-consistent calculations are presented of the cosmological, H2-dissociating UV background produced during the epoch of reionization by the sources of reionization. Large-scale
Topology and Sizes of HII Regions during Cosmic Reionization
We use the results of large-scale simulations of reionization to explore methods for characterizing the topology and sizes of HII regions during reionization. We use four independent methods for
