Non-parametric foreground subtraction for 21cm epoch of reionization experiments
Geraint Harker, Saleem Zaroubi, Gianni Bernardi +12
An obstacle to the detection of redshifted 21cm emission from the epoch of reionization (EoR) is the presence of foregrounds which exceed the cosmological signal in intensity by or…
The LOFAR EoR Data Model: (I) Effects of Noise and Instrumental Corruptions on the 21-cm Reionization Signal-Extraction Strategy
Panagiotis Labropoulos, Leon V. E. Koopmans, Vibor Jelic +11
A number of experiments are set to measure the 21-cm signal of neutral hydrogen from the Epoch of Reionization (EoR). The common denominator of these experiments are the large data…
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…
A locally anisotropic geometrical model of space-time based on CMBR
Panagiotis G. Labropoulos, Panayiotis C. Stavrinos
We study a locally anisotropic model of General Relativity in the framework of a more general geometrical structure than the Riemannian one. In this model the observable anisotropy…
