Globular cluster-massive black hole interactions in galactic centers

TL;DR

This paper discusses how globular clusters interacting with supermassive black holes in galactic centers can explain mass accumulation and influence galaxy evolution, highlighting the feedback mechanisms involved.

Contribution

It introduces the globular cluster merger scenario as a key process in galactic center mass buildup and explores the astrophysical implications of these interactions.

Findings

Globular clusters can significantly contribute to mass accumulation in galactic centers.

Interactions between globular clusters and black holes involve complex feedback mechanisms.

The scenario explains observed properties of galactic nuclei.

Abstract

Many, if not all, galaxies host massive compact objects at their centers. They are present as singularities (super massive black holes) or high density star clusters (nuclear tar clusters). In some cases they coexist, and interact more or less strongly. In this short paper I will talk of the 'merger' globular cluster scenario, which has been shown in the past to be an explanation of the substantial mass accumulation in galactic centers. In particular, I will present the many astrophysical implications of such scenario pointing the attention on the mutual feedback of orbitally decaying globular clusters with massive and super massive black holes.
