Radio Interferometric Calibration Using The SAGE Algorithm
S. Kazemi, S. Yatawatta, S. Zaroubi +3
The aim of the new generation of radio synthesis arrays such as LOFAR and SKA is to achieve much higher sensitivity, resolution and frequency coverage than what is available now, e…
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…
Double-double radio galaxies: further insights into the formation of the radio structures
Catherine Brocksopp, Christian Kaiser, Arno Schoenmakers +1
Double-double radio galaxies (DDRGs) offer a unique opportunity for us to study multiple episodes of jet activity in large-scale radio sources. We use radio data from the Very Larg…
Realistic Simulations of the Galactic Polarized Foreground: Consequences for 21-cm Reionization Detection Experiments
Vibor Jelić, Saleem Zaroubi, Panagiotis Labropoulos +3
Experiments designed to measure the redshifted 21~cm line from the Epoch of Reionization (EoR) are challenged by strong astrophysical foreground contamination, ionospheric distorti…
Constraints on the flux of Ultra-High Energy neutrinos from WSRT observations
S. Buitink, O. Scholten, J. Bacelar +7
Ultra-high energy (UHE) neutrinos and cosmic rays initiate particle cascades underneath the Moon's surface. These cascades have a negative charge excess and radiate Cherenkov radio…
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…
