Updated Bounds on Axion-Like Particles from X-ray Observations
Simon Schallmoser, Sven Krippendorf, Francesca Chadha-Day +1
In this work we revisit five different point sources within or behind galaxy clusters in order to constrain the coupling constant between axion-like particles (ALPs) and photons. W…
Accelerating the search for Axion-Like Particles with machine learning
Francesca Day, Sven Krippendorf
Machine learning (ML) techniques have been applied with tremendous success in many areas of physics. In this work, we use ML to place bounds on the coupling between photons and axi…
Searching for Axion-Like Particles with X-ray Polarimeters
Francesca Day, Sven Krippendorf
X-ray telescopes are an exceptional tool for searching for new fundamental physics. In particular, X-ray observations have already placed world-leading bounds on the interaction be…
Projected bounds on ALPs from Athena
Joseph P. Conlon, Francesca Day, Nicholas Jennings +2
Galaxy clusters represent excellent laboratories to search for Axion-Like Particles (ALPs). They contain magnetic fields which can induce quasi-sinusoidal oscillations in the X-ray…
Consistency of Hitomi, XMM-Newton and Chandra 3.5 keV data from Perseus
Joseph P. Conlon, Francesca Day, Nicholas Jennings +2
\emph{Hitomi} observations of Perseus with the Soft X-ray Spectrometer (SXS) provide a high-resolution look at the 3.5 keV feature reported by multiple groups in the Perseus cluste…
Axion decay constants away from the lamppost
Joseph P. Conlon, Sven Krippendorf
It is unknown whether a bound on axion field ranges exists within quantum gravity. We study axion field ranges using extended supersymmetry, in particular allowing an analysis with…
