Astronomers spot hard X-ray emissions from a nearby supernova remnant Cassiopeia A

(Phys.org)—A nearby young supernova remnant named Cassiopeia A is an excellent candidate for astrophysical observations regarding supernova explosion processes. One of the recent studies focuses on hard X-ray emissions from this source, describing a non-thermal continuum emission for the first time. A paper detailing the findings appeared online on May 2 on the arXiv pre-print server.
