Galaxy Clusters as Tele-ALP-scopes

Triangular Seminar Joe Conlon (Oxford)

16:30 KCL
room SMinus2.23

Galaxy clusters are the most efficient convertors of axion-like particles to photons in the universe. I discuss the physics and phenomenology of ALPs, and describe their astrophysical implications, with particular reference to the recently observed 3.5 keV X-ray line that is a candidate for a dark matter decay line.
