Query: Radiation and energy release in a background field of axion-like dark
  matter   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.
