General Relativistic Precession Model (GRPM) is a model that can help study the nature of plasma processes in black hole systems. Plasma is the particle in an ionised state that travels around at the outskirts of black holes. These particles fall into the black hole or escape in the form of jets. The GRPM was developed by researchers from the Indian Institute of Astrophysics (IIA), an autonomous institute under the Department of Science and Technology.
