DESCRIPTION:Speakers: Samuel Witte (GRAPPA Institute\, Univ Amsterdam)\nTh
 e most promising indirect search for the existence of axion dark matter us
 es radio telescopes to look for narrow spectral lines generated in the mag
 netospheres of neutron stars. Unfortunately\, a large list of theoretical 
 uncertainties has prevented this search strategy from being accepted as ro
 bust. In this talk I will present a novel end-to-end pipeline that traces 
 individual photon trajectories from their point of genesis in the magnetos
 phere to asymptotic distances. This method allows one assess many of the o
 utstanding uncertainties\, including: (1) do refraction and reflection ind
 uce strong inhomogeneous features in the flux\, (2) can refraction induce 
 premature axion-photon de-phasing\, (3) what is the expected width of the 
 line\, (4) does the flux have a strong time-dependence\, and (5) can these
  radio photons be efficiently absorbed.\n\nhttps://indico.ific.uv.es/event
