Relativistic reflection
Relativistic reflection is a phenomenon in relativity in which light from the corona of a black hole reflects off of its accretion disk, distorting the disk’s emission spectrum. Relativistic effects, such as gravitational redshift and Doppler shift, further distort this spectrum. The specific spectrum emitted is dependent on the properties of the disk, corona, and the black hole itself; analyzing the reflection spectrum of a black hole’s disk can therefore provide information about the geometry of the black hole and its surrounding region.
