Precise predictions and new insights for atomic ionization from the Migdal effect

P Cox, MJ Dolan, C McCabe, HM Quiney

Journal article  |  2023  |  Physical Review D

The scattering of neutral particles by an atomic nucleus can lead to electronic ionization and excitation through a process known ..

Dark matter pollution in the Diffuse Supernova Neutrino Background

NF Bell, MJ Dolan, S Robles

Journal article  |  2022  |  Journal of Cosmology and Astroparticle Physics

The Hyper-Kamiokande (HyperK) experiment is expected to precisely measure the Diffuse Supernova Neutrino Background (DSNB). This r..

Advancing globular cluster constraints on the axion-photon coupling

MJ Dolan, FJ Hiskens, RR Volkas

Journal article  |  2022  |  Journal of Cosmology and Astroparticle Physics
