  2. 8. Testing the far UV with an axion coupled to photons
    Mario Reig Lopez (University of Oxford)

    After a brief introduction to axions in string theory, discussing their quality and the origin of their couplings, I will review recent progress in understanding their properties in different string theories from type IIB to heterotic string theories. I will show how the discovery of a light ALP — that is, above the QCD line — is incompatible with unification and heterotic string theory....

  3. 1. Scaling in axion string networks
    Prof. Mark Hindmarsh (University of Helsinki, University of Sussex)
    13/02/2025, 11:30

    In the post-inflationary axion scenario, axions are produced by axion strings. A crucial parameter for the prediction of the axion dark matter mass is the length per unit volume of axion strings at the time of the QCD transition. This can be established only by numerical simulations, which are limited in volume and time, and must be extrapolated to physical values. After a brief history of...

  6. 4. High-frequency gravitational waves shining in photons in Astrophysical magnetic fields
    Alessandro Lella

    High-frequency gravitational waves (f\gtrsimf≳~MHz) are a smoking gun for the existence of exotic physics. In particular, GW backgrounds lying in the high-frequency would allow one to probe inflation, first-order phase transitions, topological defects and primordial black holes. The lack of current and future gravitational wave experiments sensitive at those frequencies leads to the need of...
