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…
Axion-like particle oscillations
Francesca Chadha-Day
String theory compactifications may generate many light axion-like particles (ALPs) with weak couplings to electromagnetism. In general, a large number of ALPs may exist, with a li…
Axion Dark Matter: What is it and Why Now?
Francesca Chadha-Day, John Ellis, David J. E. Marsh
The axion has emerged in recent years as a leading particle candidate to provide the mysterious dark matter in the cosmos, as we review here for a general scientific audience. We d…
Axion Quasiparticles for Axion Dark Matter Detection
Jan Schütte-Engel, David J. E. Marsh, Alexander J. Millar +7
It has been suggested that certain antiferromagnetic topological insulators contain axion quasiparticles (AQs), and that such materials could be used to detect axion dark matter (D…
