# New examples of Hawking radiation from acoustic black holes

## TL;DR

This paper investigates Hawking radiation in complex acoustic black holes, including those with corners, expanding understanding of quantum effects in analogue gravity systems.

## Contribution

It introduces analysis of Hawking radiation in more complex acoustic black holes, such as those with corner points, beyond previously studied simple models.

## Key findings

- Hawking radiation observed in complex acoustic black holes.
- Black holes with corners can emit Hawking radiation.
- Extended understanding of analogue black hole quantum effects.

## Abstract

Rotating acoustic metrics may have black holes inside the ergosphere. Simple cases of acoustic black holes were studied in the references [21], [4]. In the present paper we study the Hawking radiation for more complicated cases of acoustic black holes including black holes that have corner points.
