We discuss different astrophysical targets, such as dwarf spheroidal galaxies, the Galactic Center and halo, and galaxy clusters. The presence of an ambient radiation field leads to a stimulated enhancement of the decay rate; depending on the environment and the mass of the axion, the effect of stimulated emission may amplify the photon flux by serval orders of magnitude. For axion-photon couplings allowed by astrophysical and laboratory constraints (and possibly favored by stellar cooling), we find the signal to be within the reach of next-generation radio telescopes such as the Square Kilometer Array.", optnote="WOS:000461450100002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3944), last updated on Thu, 28 Mar 2019 09:31:15 +0000", issn="1475-7516", doi="10.1088/1475-7516/2019/03/027", opturl="https://arxiv.org/abs/1811.08436", opturl="https://doi.org/10.1088/1475-7516/2019/03/027", language="English" }
