Description
At great distances from our galaxy, the Milky Way, highly energetic bursts were detected over short periods. Extensive research has been conducted based on these bursts, making this a highly complex and detailed topic call Gamma ray bursts (GRBs).
These gamma-ray bursts are theorized to have a central engine responsible for emitting a final jet and an accretion disk around a supermassive black hole as the central engine of these gamma-ray bursts. Accretion refers to the process of material falling inward toward the inner regions, ultimately collapsing onto the black hole.
There are numerous processes for this accretion disk, which are very complex, and various parameters can be examined concerning these accretion disks.
I will discuss gamma-ray bursts, the types of sources that create them, and the resulting central engine. Finally, I will delve into the accretion disk around the black hole as the central engine of these bursts, examining a specific parameter related to mass accumulation on these disks.
Additionally, in an accretion disk, material accumulates, and depending on the viscous force resulting from the turbulence in the disk, mass accumulation varies at different radii. Different layers of varying mass and density exist in different regions of the gaseous accretion disk, leading to an inhomogeneous distribution of mass. I will discuss this mass accumulation.
This inhomogeneous mass distribution is the reason for having a final jet with a shock-like structure.
