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…
Ultralight Dark Matter Statistics for Pulsar Timing Detection
Kimberly K. Boddy, Jeff A. Dror, Austin Lam
Fluctuations in ultralight dark matter produce significant metric perturbations, which may be detected by monitoring the arrival times of light from millisecond pulsars. While sear…
On Pulsar Timing Detection of Ultralight Vector Dark Matter
Jeff A. Dror, Qiushi Wei
Ultralight vector dark matter induces metric fluctuations that generate timing residuals in the arrival times of pulsar emissions through two distinct modes: a fast mode, sourced b…
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…
Astrometric Detection of Ultralight Dark Matter
Jeff A. Dror, Sarunas Verner
Ultralight dark matter induces time-dependent perturbations in the spacetime metric, enabling its gravitational direct detection. In this work, we propose using astrometry to detec…
