Radio Interferometric Calibration Using The SAGE Algorithm
Sarod Yatawatta, Saleem Zaroubi, Ger de Bruyn +2
Radio Interferometry is an essential method for astronomical observations. Self-calibration techniques have increased the quality of the radio astronomical observations (and hence…
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…
On the 3 dimensional structure of edge-on disk galaxies
M. Pohlen, S. Zaroubi, R. F. Peletier +1
A simple algorithm is employed to deproject the two dimensional images of a pilot sample of 12 high-quality images of edge-on disk galaxies and to study their intrinsic 3 dimension…
LOFAR as a Probe of the Sources of Cosmological Reionisation
Saleem Zaroubi, Joseph Silk
We propose use of the thickness of the ionisation front as a discriminant between alternative modes of reionisation in the early universe, by stars or by miniquasars. Assuming a ph…
Cosmic Flows: Review of Recent Developments
Saleem Zaroubi
I review the recent developments in the analysis of cosmic flow data, in particular, latest results of bulk flow measurements, comparison between redshift and peculiar velocity cat…
Detecting HeliumII reionization from a sudden injection of entropy in the intergalactic medium
Tom Theuns, Saleem Zaroubi, Tae-Sun Kim
The temperature of the low-density intergalactic medium is set by the balance between adiabatic cooling resulting from the expansion of the universe, and photo-heating by the UV-ba…
