Active black holes have a pancake-shaped structure around them called an accretion disk, which contains hot, electrically charged gas. The plasma that makes up the accretion disk comes from ...

These accrete—meaning merge and combine—into an accretion disk that surrounds the SMBH. (Stars, in turn, can have their own accretion disks, so it’s accretion all the way down.) For certain ...

Abstract: Understanding the plasma physics of accretion disks and coronae around black holes is crucial for interpreting the radiation observed from these systems. However, these plasmas span several ...
