Measuring the Spins of Accreting Black Holes

McClintock, Jeffrey E., Narayan, Ramesh, Davis, Shane W. et al.

Understand

A typical galaxy is thought to contain tens of millions of stellar-mass black holes, the collapsed remnants of once massive stars, and a single nuclear supermassive black hole.

  • Both classes of black holes accrete gas from their environments.
  • The accreting gas forms a flattened orbiting structure known as an accretion disk.
  • During the past several years, it has become possible to obtain measurements of the spins of the two classes of black holes by modeling the X-ray emission from their accretion disks.
