Description

This week-long CERN-Korea TH Institute will concentrate on recent progress and open questions in axion physics.

Topics to be covered include:
(1) The QCD axion: couplings, laboratory/astro/cosmo constraints.
(2) Axion cosmology: thermal and non-thermal production, axion dark matter, structure formation. Topological defects.
(3) Theoretical ideas on axion detection: from stellar probes to lab-based proposals for axion detection, highlighting new ideas.
(4) Ultra-light axion-like particles and cosmological implications.

      The Axion Echo method and the Big Flow 1h 4/3-006 - TH Conference Room

      Electromagnetic radiation with angular frequency half the
      axion mass stimulates the decay of dark matter axions and
      produces an echo, i.e. faint electromagnetic radiation
      traveling in the opposite direction. Thus one may search
      for axion dark matter by sending out to space a powerful
      beam of electromagnetic radiation and listening for its
      echo. The method is particularly attractive if the Earth
      is bathed in a cold axion flow of known direction. The
      Caustic Ring Model of the Milky Way halo predicts such a
      cold flow with high local density, called the Big Flow. The direction of the Big Flow is determined from triangular
      features in the IRAS and GAIA maps of the Milky Way with a
      precision of order 0.5 degree of arc.
