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…
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…
Time-evolution of ionization and heating around first stars and miniquasars
Rajat M. Thomas, Saleem Zaroubi
A one dimensional radiative transfer code is developed to track the ionization and heating pattern around the first miniquasars and Population III stars. The code follows the evolu…
Heating of the Intergalactic Medium by Primordial Miniquasars
Saleem Zaroubi, Rajat M. Thomas, Naoshi Sugiyama +1
A simple analytical model is used to calculate the X-ray heating of the IGM for a range of black hole masses. This process is efficient enough to decouple the spin temperature of t…
