The burgeoning rise of the 21-cm forest I: constraints on the optical depth of the intergalactic medium at
Chanasorn Kongprachaya, Gianni Bernardi, Emilio Ceccotti +3
The redshifted 21-cm line is a promising probe of the Epoch of Reionization, during which the first generation of stars ionized the InterGalactic Medium (IGM). We aimed to constrai…
A direction-dependent framework for visibility plane mosaicing and primary beam correction
Keegan S. Trehaeven, Cyril Tasse, Oleg Smirnov +1
With the increasing sensitivity of modern radio interferometers, it has become important to image objects larger than the field of view while optimising sensitivity and image fidel…
The MeerKAT Galaxy Cluster Legacy Survey -- II. Catalogue of the diffuse radio emission in MeerKAT-GCLS clusters
Konstantinos Kolokythas, Tiziana Venturi, Kenda Knowles +7
We present a follow-up study focused on cluster-scale diffuse radio emissions in 115 galaxy clusters in the Southern sky, using full-resolution (7.8") and tapered low-resolution (1…
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…
