Wide field polarimetry around the Perseus cluster at 350 MHz
M. A. Brentjens
This paper investigates the fascinating diffuse polarization structures at 350 MHz that have previously been tentatively attributed to the Perseus cluster and, more specifically, t…
Deep multi-frequency rotation measure tomography of the galaxy cluster A2255
R. F. Pizzo, A. G. de Bruyn, G. Bernardi +1
We aim to unveil their 3-dimensional geometry of Abell 2255 through WSRT observations at 18, 21, 25, 85, and 200 cm. The polarization images of the cluster were processed through r…
Power spectrum extraction for redshifted 21-cm epoch of reionization experiments: the LOFAR case
Geraint Harker, Saleem Zaroubi, Gianni Bernardi +13
One of the aims of the Low Frequency Array (LOFAR) Epoch of Reionization (EoR) project is to measure the power spectrum of variations in the intensity of redshifted 21-cm radiation…
Foregrounds for observations of the cosmological 21 cm line: II. Westerbork observations of the fields around 3C196 and the North Celestial Pole
G. Bernardi, A. G. de Bruyn, G. Harker +11
In the coming years a new insight into galaxy formation and the thermal history of the Universe is expected to come from the detection of the highly redshifted cosmological 21 cm l…
