Supermassive Primordial Black Holes From Inflation

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, Albert Stebbins, | Summary: There is controversy surrounding the origin and evolution of our universe’s largest supermassive black holes (SMBHs). In this study, we consider the possibility that some of these black holes formed from the direct collapse of primordial density […]
