Description
In this talk I will review two different works that search for axion-like particles (ALPs) decay into two photons. Assuming dark matter (DM) to be in the form of ALPs, we study prospects to detect ALPs with the upcoming near-infrared telescope SPHEREx taking into account signals from the DM halos of dwarf spheroidal galaxies, the Large Magellanic Cloud and the Milky Way. In addition, we show the analysis of real x-ray data taken by eROSITA from the Large Magellanic Cloud, searching for the same signal. All together we show prospects on the axion-photon coupling in the 0.5-3 eV ALP mass range, and exclusion limits on the 2-18 keV mass range.
