GW190521 May Be an Intermediate-mass Ratio Inspiral
Abstract GW190521 is the first confident observation of a binary black hole merger with total mass <?CDATA $M\gt 100\,{M}_{\odot }$?> . Given the lack of observational constraints at these masses, we analyze GW190521 considering two different priors for the binary’s masses: uniform in mass ratio and source-frame total mass, and …
