The possible origin of the mini-spiral in the nuclear disk of the Galaxy as a result of the super-reflection instability

It is shown that the mini-spiral in the nuclear disk of the Galaxy could arise as a result of super-reflection instability in the disk. This instability develops at a break in the profile of the disk rotation. The structure of the perturbation obtained via numerical modeling is visually similar to t...

Summary:It is shown that the mini-spiral in the nuclear disk of the Galaxy could arise as a result of super-reflection instability in the disk. This instability develops at a break in the profile of the disk rotation. The structure of the perturbation obtained via numerical modeling is visually similar to the observed mini-spiral.
