# Black hole astrophysics with HAWC, the High Altitude Water Cherenkov gamma-ray observatory

## TL;DR

This paper discusses HAWC's capabilities in detecting and studying black hole-related phenomena in the gamma-ray spectrum, including observations of supermassive black holes and transient events.

## Contribution

It presents new observational data from HAWC on black hole related objects and demonstrates its potential in high-energy astrophysics research.

## Key findings

- Detection of supermassive black holes in the near Universe
- Daily gamma-ray light curves of Mrk 421 and Mrk 501
- Compilation of studies on black hole related objects

## Abstract

The HAWC gamma-ray observatory is a wide field of view and high duty cycle $\gamma$-ray detector investigating the 0.1 - 100 TeV energy range. It has detected supermassive black holes in the near Universe, and is seeking to detect black hole related objects like gamma-ray bursts, Galactic binary systems, primordial black holes and gravitational wave mergers. Daily light curves of the BL Lac objects Mrk 421 and Mrk 501 are presented here, together with a compilation of studies of black hole related objects.
