Close Pulsar Pairs See Dark Matter Substructure through the Gravitational-Wave Background
Abhiram Cherukupalli, Vincent S. H. Lee, Kim V. Berghaus +1
Pulsar timing arrays detect signals from dark matter substructure, but a nanohertz gravitational-wave background (GWB) severely degrades their sensitivity. We show that timing puls…
Pulsar Timing Sensitivity to Dark Matter Substructure in the Presence of a Stochastic Gravitational-Wave Background
Abhiram Cherukupalli, Vincent S. H. Lee, Kim Berghaus +1
Pulsar timing arrays (PTAs) can detect dark matter (DM) substructure through the small shifts a transiting DM subhalo imprints on pulse arrival times. Recently found evidence for a…
The Migdal effect in Semiconductors for the Effective Field Theory of Dark Matter Direct Detection
Kim V. Berghaus, Rouven Essig, Megan H. McDuffie
The Migdal effect in semiconductors, prompt ionization from a primary nuclear scattering event, can be described across all kinematic regimes using an effective field theory that e…
Classical equipartition dynamics between axions and non-Abelian gauge fields
Kim V. Berghaus, Adrien Florio, M. Laine +1
Motivated by axion-like inflation and its warm embedding within the Standard Model, we study the early stages of the energy transfer between an axion condensate and an SU(2) gauge…
