Detectability of the 21 cm-CMB cross-correlation from the EoR (2009)

Tashiro, Hiroyuki, Aghanim, Nabila, Langer, Mathieu, Douspis, Marian, Zaroubi, Saleem, Jelic, Vibor

The 21-cm line fluctuations and the cosmic microwave background (CMB) are powerful probes of the epoch of reionisation of the universe. We study the potential of the cross-correlation between 21-cm...

Cross-correlation Study between the Cosmological 21-cm Signal and the kinetic Sunyaev-Zel'dovich effect (2009)

Jelic, Vibor, Zaroubi, Saleem, Aghanim, Nabila, Douspis, Marian, Koopmans, Leon V. E., Langer, Mathieu, ...

The Universe's Epoch of Reionization (EoR) can be studied using a number of observational probes that provide complementary or corroborating information. Each of these probes suffers from its own...

Non-parametric foreground subtraction for 21cm epoch of reionization experiments (2009)

Harker, Geraint, Zaroubi, Saleem, Bernardi, Gianni, Brentjens, Michiel A., De Bruyn, A. G., Ciardi, Benedetta, ...

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 orders of magnitude....

The LOFAR EoR Data Model: (I) Effects of Noise and Instrumental Corruptions on the 21-cm Reionization Signal-Extraction Strategy (2009)

Labropoulos, Panagiotis, Koopmans, Leon V. E., Jelic, Vibor, Yatawatta, Sarod, Thomas, Rajat M., Bernardi, Gianni, ...

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 sets produced,...

Detection and extraction of signals from the epoch of reionization using higher order one-point statistics (2008)

Harker, Geraint J. A., Zaroubi, Saleem, Thomas, Rajat M., Jelic, Vibor, Labropoulos, Panagiotis, Mellema, Garrelt, ...

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 challenging to extract...

Fast Large-Scale Reionization Simulations (2008)

Thomas, Rajat M., Zaroubi, Saleem, Ciardi, Benedetta, Pawlik, Andreas H., Labropoulos, Panagiotis, Jelic, Vibor, ...

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-only simulations...

Foreground simulations for the LOFAR - Epoch of Reionization Experiment (2008)

Jelic, Vibor, Zaroubi, Saleem, Labropoulos, Panagiotis, Thomas, Rajat M., Bernardi, Gianni, Brentjens, Michiel A., ...

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 order to reliably...
