# Radiation and energy release in a background field of axion-like dark matter

## TL;DR

This paper explores how a background of axion-like dark matter combined with galactic magnetic fields can produce significant radiation energy release, revealing new interactions between dark matter and electromagnetic fields.

## Contribution

It demonstrates a novel mechanism for energy transfer from fuzzy dark matter to electromagnetic radiation in the presence of galactic magnetic fields.

## Key findings

- Radiation frequency matches axion-like background oscillations
- Energy transfer occurs between dark matter and electromagnetic sectors
- Energy release rate is significant compared to galactic magnetic field energy

## Abstract

We find that a fuzzy dark matter background and the mG scale magnetic field in the galactic center can give rise to a radiation with a very large energy release. The frequency of the radiation field is the same as the frequency of the oscillating axion-like background field. We show that there is an energy transfer between the fuzzy dark matter sector and the electromagnetic sector because of the presence of the generated radiation field and the galactic magnetic field. The energy release rate of radiation is found to be very slow in comparison with the energy of fuzzy dark matter but could be significant comparing with the energy of galactic magnetic field in the source region. Using this example, we show that the fuzzy dark matter together with a large scale magnetic field is possible to give rise to fruitful physics.
