CRASH2: colored packets and other updates
A. Maselli, B. Ciardi, A. Kanekar +1
In this paper we report on the improvements implemented in the cosmological radiative transfer code CRASH. In particular we present a new multi-frequency algorithm for spectra samp…
Fast Large-Scale Reionization Simulations
Rajat M. Thomas, Saleem Zaroubi, Benedetta Ciardi +12
We present an efficient method to generate large simulations of the Epoch of Reionization (EoR) without the need for a full 3-dimensional radiative transfer code. Large dark-matter…
Detection and extraction of signals from the epoch of reionization using higher order one-point statistics
Geraint J. A. Harker, Saleem Zaroubi, Rajat M. Thomas +13
Detecting redshifted 21cm emission from neutral hydrogen in the early Universe promises to give direct constraints on the epoch of reionization (EoR). It will, though, be very chal…
The search for Population III stars
Sperello di Serego Alighieri, Jaron Kurk, Benedetta Ciardi +3
Population III stars, the first generation of stars formed from primordial Big Bang material with a top-heavy IMF, should contribute substantially to the Universe reionization and…
Foreground simulations for the LOFAR - Epoch of Reionization Experiment
Vibor Jelic, Saleem Zaroubi, Panagiotis Labropoulos +10
Future high redshift 21-cm experiments will suffer from a high degree of contamination, due both to astrophysical foregrounds and to non-astrophysical and instrumental effects. In…
CRASH_alpha: coupling continuum and line radiative transfer
M. Pierleoni, A. Maselli, B. Ciardi
In this paper we present CRASH_alpha, the first radiative transfer code for cosmological application that follows the parallel propagation of Ly_alpha and ionizing photons. CRASH_a…
