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…

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…
