As the space.com report states "A team of researchers led by Erini Lambrides of Johns Hopkins University (JHU) in Baltimore, Maryland has spotted 28 supermassive black holes that have been masquerading as other cosmic objects using a host of telescopes including NASA's Chandra X-ray Observatory, Hubble Space Telescope and Spitzer Space Telescope. The team observed these black holes which lie 5 billion light-years or more away within the Chandra Deep Field-South (CDF-S), the deepest X-ray image ever taken."
The more SMBH identified and documented, the more fun it becomes. Consider reports on PBH (primordial black holes). There is a finite volume of space surveyed in these black hole studies with more reported it seems. The early universe and process(s) that formed various structures in BB cosmology like PBH, SMBH, is very different than where we live today and observe operating in the Milky Way today.
