DESCRIPTION:Axion-like particles (ALPs) are a conjectured Beyond-the-Stand
 ard-Model particle with good theoretical motivation. They \nare characteri
 sed by interconversion of photons and ALPs in astrophysical magnetic field
 s.\nAt X-ray energies galaxy clusters are the most efficient interconverto
 rs of axion-like particles to photons in the universe.\nI discuss the phys
 ics and phenomenology of ALPs\, in particular within galaxy clusters\, and
  describe their astrophysical implications in relation\nto two topics: the
  recently observed 3.5 keV line and the use of small-scale structure withi
 n the X-ray thermal bremsstrahlung spectrum\nof galaxy clusters to search 
 for/constrain ALPs.
