Have astronomers found the signatures of the very first black holes formed through the collapse of gas clouds?
... that the seeds of SMBHs are formed via a process known as directcollapse black holes (DCBHs), whereby a gas cloud composed of atomic hydrogen collapses isothermally. This method also has its problems, as the likely outcome of such...
