SUMMARY:Particle Physics Beyond the Standard Model with X-ray Studies of G
 alaxy Clusters - Prof. Christopher Reynolds (IoA)

CONTACT:Dr Annelies Mortier
DESCRIPTION:Clusters of galaxies provide superb laboratories for exploring
  new particle physics.  They represent the most massive dark matter object
 s in the Universe\, making them an important laboratory for probing dark m
 atter decay and annihilation signatures.  However\, in this talk\, I will 
 highlight how the transparency (or lack thereof) of the magnetized intracl
 uster medium (ICM) to X-rays can be a powerful probe of axion-sector physi
 cs.  I will present new data from the Chandra X-ray Observatory for the Pe
 rseus cluster which allows us to set constraints on the existence of low-m
 ass axion-like particles which exceed those possible from the next-generat
 ion laboratory and ground-based searches. I shall finish by discussing the
  future prospects and limitations of these studies.
