Vlad Dumitru Berlea, Arooj Asif, Merlin F. Barschke +18
ULTRASAT (ULtra-violet TRansient Astronomy SATellite) is a wide-angle space telescope that will perform a deep time-resolved all-sky survey in the near-ultraviolet (NUV) spectrum.…
Coma cluster -ray and radio emission is consistent with a secondary electron origin for the radio halo
Doron Kushnir, Uri Keshet, Eli Waxman
Observations of diffuse, non-thermal radio emission spanning several megaparsecs have been documented in over 100 galaxy clusters. This emission, classified as giant radio halos (G…
