Influence of a black hole's spin: First evidence of precession in ultraluminous accretion disks
Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black hole) exhibits a precessional motion driven by the black hole's spin. This finding underscores the potential of this spin to be the primary driver of the periodic fluctuations in luminosity observed within these ultraluminous accretion disks.
