A MeerKAT view on galaxy clusters
G. Bernardi, T. Venturi, R. Cassano +8
Almost two decades of observations of radio emission in galaxy clusters have proven the existence of relativistic particles and magnetic fields that generate extended synchrotron e…
Limiting Magnetic Fields in the Cosmic Web with Diffuse Radio Emission
S. Brown, T. Vernstrom, E. Carretti +7
We set limits on the presence of the synchrotron cosmic web through the cross-correlation of the 2.3 GHz S-PASS survey with a model of the local cosmic web derived from constrained…
A search for Fast Radio Bursts at low frequencies with Murchison Widefield Array high time resolution imaging
S. J. Tingay, C. M. Trott, R. B. Wayth +26
We present the results of a pilot study search for Fast Radio Bursts (FRBs) using the Murchison Widefield Array (MWA) at low frequencies (139 - 170 MHz). We utilised MWA data obtai…
Polarization leakage in Epoch of Reionization windows: I. LOFAR observations of the 3C196 field
K. M. B. Asad, L. V. E. Koopmans, V. Jelić +25
Detection of the 21-cm signal coming from the epoch of reionization (EoR) is challenging especially because, even after removing the foregrounds, the residual Stokes maps conta…
Cluster Radio Halos at the crossroads between astrophysics and cosmology in the SKA era
R. Cassano, G. Bernardi, G. Brunetti +16
Giant Radio Halos (RH) are diffuse, Mpc-sized, synchrotron radio sources observed in a fraction of merging galaxy clusters. The current scenario for the origin of RHs assumes that…
Constraining the epoch of reionization with the variance statistic: simulations of the LOFAR case
Ajinkya H. Patil, Saleem Zaroubi, Emma Chapman +27
Several experiments are underway to detect the cosmic redshifted 21-cm signal from neutral hydrogen from the Epoch of Reionization (EoR). Due to their very low signal-to-noise rati…
