No problem! Here's the information about the Accretion Disks Around Black Holes
Relativistic Effects in Accretion Disks:
Gravitational Redshift: Light from the inner disk loses energy as it escapes the black hole's gravity, making it appear redder.
Relativistic Doppler Effect: The high-speed motion of gas causes blueshifting on the side moving toward us and redshifting on the side moving away
3 Frame Dragging (Lense-Thirring Effect): A spinning black hole twists spacetime, pulling the disk along with it
