Astronomical Image Blurring from Transversely Correlated Quantum Gravity Fluctuations
Vincent S. H. Lee, Kathryn M. Zurek, Yanbei Chen
Quantum fluctuations in spacetime can, in some cases, lead to distortion in astronomical images of faraway objects. In particular, a stochastic model of quantum gravity predicts an…
The NANOGrav 15-year Data Set: Search for Signals from New Physics
Adeela Afzal, Gabriella Agazie, Akash Anumarlapudi +120
The 15-year pulsar timing data set collected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) shows positive evidence for the presence of a low-freque…
Macroscopic Dark Matter Detection with Gravitational Wave Experiments
Yufeng Du, Vincent S. H. Lee, Yikun Wang +1
We study signatures of macroscopic dark matter (DM) in current and future gravitational wave (GW) experiments. Transiting DM with a mass of kg that saturates the…
