# Similarity and diversity of black holes - view from the Very High Energies

## TL;DR

This review discusses recent very high energy gamma-ray observations of black hole systems, highlighting their similarities in jet launching mechanisms and their diverse manifestations across different black hole classes.

## Contribution

It provides a comprehensive overview of recent gamma-ray results, emphasizing both the commonalities and differences among black hole systems.

## Key findings

- Black hole systems share similar jet launching mechanisms.
- Diversity in gamma-ray emissions among different black hole classes.
- Recent observations reveal both similarities and differences in high-energy phenomena.

## Abstract

Active galactic nuclei, hosting supermassive black holes and launching relativistic jets, are the most numerous objects on the gamma-ray sky. At the other end of the mass scale, phenomena related to stellar mass black holes, in particular gamma-ray bursts and microquasars, are also seen on the gamma-ray sky. While all of them are thought to launch relativistic jets, the diversity even within each of these classes is enormous. In this review, I will discuss recent very high energy gamma-ray results that underline both the similarity of the black hole systems, as well as their diversity.
