Popis:	We study prospects to detect axion-like particles (ALPs) with the upcoming near-infrared telescope SPHEREx. The signal under investigation is the ALP decay into two photons. Assuming dark matter (DM) to be in the form of ALPs, we analyze the signal from the DM halos of dwarf spheroidal galaxies, the Large Magellanic Cloud and the Milky Way. We find that SPHEREx can significantly improve current limits on the axion-photon coupling in the 0.5-3 eV ALP mass range. Comment: 8 pages, 2 figures
