Compact Dark Matter with Globular Cluster Pulsars
Soobeom Chung, Jeff A. Dror
Pulsars are exceptionally stable clocks, and a compact dark-matter object passing near the line of sight to a pulsar delays its pulses through the Shapiro effect. The number of det…
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…
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…
Axion Production and Detection Using a Dual NMR-type Experiment
Jeff A. Dror, Qiushi Wei, Fengwei Yang
Axions that couple to nuclear spins via the axial current interaction can be both produced and detected using nuclear magnetic resonance (NMR) techniques. In this scheme, nuclei dr…
Probing Picohertz Gravitational Waves with Pulsars
Qinyuan Zheng, Chiara M. F. Mingarelli, William DeRocco +3
With periods much longer than the duration of current pulsar timing surveys, gravitational waves in the picohertz (pHz) regime are not detectable in the typical analysis framework…
