Axions and ALPs: a very short introduction

David J. E. Marsh

The QCD axion was originally predicted as a dynamical solution to the strong CP problem. Axion like particles (ALPs) are also a generic prediction of many high energy physics model…

Search for axion-like dark matter through nuclear spin precession in electric and magnetic fields

C. Abel, N. J. Ayres, G. Ban +45

We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spin-precession frequencies of stored ultracold neutrons and Hg atoms for an a…

Using the Full Power of the Cosmic Microwave Background to Probe Axion Dark Matter

Renée Hlozek, David J. E. Marsh, Daniel Grin

The cosmic microwave background (CMB) places strong constraints on models of dark matter (DM) that deviate from standard cold DM (CDM), and on initial conditions beyond the scalar…

Structure Formation and Microlensing with Axion Miniclusters

Malcolm Fairbairn, David J. E. Marsh, Jérémie Quevillon +1

If the symmetry breaking responsible for axion dark matter production occurs during the radiation-dominated epoch in the early Universe, then this produces large amplitude perturba…

The Spectrum of the Axion Dark Sector

Matthew J. Stott, David J. E. Marsh, Chakrit Pongkitivanichkul +2

Axions arise in many theoretical extensions of the Standard Model of particle physics, in particular the "string axiverse". If the axion masses, , and (effective) decay consta…

Constraining the mass of light bosonic dark matter using SDSS Lyman- forest

Eric Armengaud, Nathalie Palanque-Delabrouille, Christophe Yèche +2

If a significant fraction of the dark matter in the Universe is made of an ultra-light scalar field, named fuzzy dark matter (FDM) with a mass of the order of $10^{-22}-10^{-…
