Soft X-ray Excess in the Coma Cluster from a Cosmic Axion Background
Stephen Angus, Joseph P. Conlon, M. C. David Marsh +2
We show that the soft X-ray excess in the Coma cluster can be explained by a cosmic background of relativistic axions converting into photons in the cluster magnetic field. We prov…
A Note on the Magnitude of the Flux Superpotential
Michele Cicoli, Joseph P. Conlon, Anshuman Maharana +1
The magnitude of the flux superpotential plays a crucial role in determining the scales of IIB string compactifications after moduli stabilisation. It has been argued th…
Loop corrections to Delta N_eff in large volume models
Stephen Angus, Joseph P. Conlon, Ulrich Haisch +1
In large volume models reheating is driven by the decays of the volume modulus to the visible sector, while the decays to its axion partners result in dark radiation. In this artic…
Searching for a 0.1-1 keV Cosmic Axion Background
Joseph P. Conlon, M. C. David Marsh
Primordial decays of string theory moduli at z \sim 10^{12} naturally generate a dark radiation Cosmic Axion Background (CAB) with 0.1 - 1 keV energies. This CAB can be detected th…
The Cosmophenomenology of Axionic Dark Radiation
Joseph P. Conlon, M. C. David Marsh
Relativistic axions are good candidates for the dark radiation for which there are mounting observational hints. The primordial decays of heavy fields produce axions which are ultr…
