Description
The possible interaction of axionlike particles (ALPs) with photons would leave distinctive features in observations of gamma-ray sources. Such features include apparent oscillations in energy spectra, a reduction of the opacity of the Universe to gamma rays, as well as the possibility of a gamma-ray burst from core-collapse supernovae. In this talk I will review the latest results obtained with the Fermi Large Area Telescope and present new analyses for the gamma-ray opacity and the search for gamma-ray bursts from extragalactic supernovae. It will be shown that current and future gamma-ray observations have the sensitivity to probe ALP dark matter for ALP masses below 1e-6 eV.
