  "abstract": "Galaxy clusters contain large magnetic fields that make them excellent targets to search for ultralight Axion-Like Particles (ALPs). ALP-photon interconversion imprints quasi-sinusoidal oscillations on the X-ray spectra of point sources in or behind the cluster. The absence of substantial oscillations allows us to place bounds on $g_{a \\gamma \\gamma}$. Here the bounds from the {\\it Chandra} X-ray observations of NGC1275 are presented, as well as those predicted for the {\\it Athena} X-ray observatory, due to launch in 2028.",
