Detectable subhalo impacts in Milky Way streams
Junyang Lu, Elias Bernreuther, Tongyan Lin +3
Dark matter subhalos leave gravitational imprints in the stellar streams of the Milky Way. Observing individual strong impacts of subhalos offers a compelling way to constrain and…
Correlated signals of ultralight scalar dark matter in pulsar timing
Joshua W. Foster, Kimberly K. Boddy, Jeff A. Dror +5
Pulsar timing arrays (PTAs) are sensitive to ultralight dark matter (ULDM) in the - mass range, with existing datasets already probing otherwise op…
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…
Primordial Non-Gaussianity and the Field-Level Cramer-Rao Bound
Eugene Chen, Daniel Green, Vincent S. H. Lee
Primordial non-Gaussianity is one of the most powerful probes of the inflationary epoch. The particle spectrum relevant to inflation, including masses and spins, is encoded in the…
Physics beyond the Standard Model with the DSA-2000
Kim V. Berghaus, Yufeng Du, Vincent S. H. Lee +4
The upcoming Deep Synoptic Array 2000 (DSA-2000) will map the radio sky at GHz (eV) with unprecedented sensitivity. This will enable searches for dark matt…
Detecting gravitational signatures of dark matter with atom gradiometers
Leonardo Badurina, Yufeng Du, Vincent S. H. Lee +2
We study the purely gravitational signatures of dark matter from the ultralight to the ultraheavy mass range in proposed long-baseline atom gradiometers, focusing on terrestrial de…
