Decoupling and de Sitter Vacua in Approximate No-Scale Supergravities
M. C. David Marsh, Bert Vercnocke, Timm Wrase
We study supergravity with chiral superfields in which one of the fields has a Kähler potential of exact no-scale type. Such systems admit de Sitter (dS) solutio…
Observational consistency and future predictions for a 3.5 keV ALP to photon line
Pedro D. Alvarez, Joseph P. Conlon, Francesca V. Day +2
Motivated by the possibility of explaining the 3.5 keV line through dark matter decaying to axion-like particles that subsequently convert to photons, we study ALP-photon conversio…
The Darkness of Spin-0 Dark Radiation
M. C. David Marsh
We show that the scattering of a general spin-0 sector of dark radiation off the pre-recombination thermal plasma results in undetectably small spectral distortions of the Cosmic M…
A 3.55 keV Photon Line and its Morphology from a 3.55 keV ALP Line
Michele Cicoli, Joseph P. Conlon, M. C. David Marsh +1
Galaxy clusters can efficiently convert axion-like particles (ALPs) to photons. We propose that the recently claimed detection of a 3.55--3.57 keV line in the stacked spectra of a…
