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…
Echoes of Global Cosmic Strings
Jeff A. Dror, Antonios Kyriazis
If the Universe underwent a cosmic phase transition, it may have left behind a network of cosmic strings. When these strings arise from the breaking of a gauge symmetry, their deca…
Cosmic Axion Background Detection Using Resonant Cavity Arrays
Soobeom Chung, Jeff A. Dror
The axion is a well-motivated and generic extension of the Standard Model. If produced in the early universe, axions may still be relativistic today, forming a Cosmic Axion Backgro…
Exploring Invisible New Physics with Exotic Pion Decays
Wolfgang Altmannshofer, Jeff A. Dror, Pierce Giffin +5
We study the sensitivity of past and future stopped-pion experiments to light, invisible dark sector particles produced in exotic pion decays. We consider two-body decays involving…
