“Echos of the Early Universe in Axion Haloscopes”

Nick Rodd

(Dep. of Theoretical Physics, CERN))

Abstract:

The coming decade will bring dramatic improvement in the axion dark-matter

program as new experimental designs move beyond the proof of principle stage.

In this talk I will outline two signals beyond dark matter that these instruments

could discover. The first is a population of relativistic axions that were produced

in the early universe and persist as a residual Cosmic axion Background (CaB).

The second is high-frequency gravitational waves; I will outline how exploiting

an analogy between axion and gravitational-wave electrodynamics allows for

axion haloscopes to be converted into gravitational-wave telescopes.
