Testing General Relativity with Individual Supermassive Black Hole Binaries
Qinyuan Zheng, Bjorn Larsen, Ellis Eisenberg +1
We develop a unified framework for testing gravity beyond General Relativity (GR) with continuous gravitational waves (CWs) from individual supermassive black hole binaries (SMBHBs…
Gravity Echoes from Supermassive Black Hole Binaries
Qinyuan Zheng, Bence Bécsy, Chiara M. F. Mingarelli
Pulsar timing arrays record gravitational waves from supermassive black hole binaries at two spacetime points: an Earth term, measured when the wave passes the Earth, and a pulsar…
Fingerprints of Individual Supermassive Black Hole Binaries in Pulsar Timing Arrays
Chiara M. F. Mingarelli, Bjorn Larsen, Ellis Eisenberg +2
With evidence for a nanoHertz gravitational-wave background now established by Pulsar Timing Arrays, the search focuses on identifying individual supermassive black hole binaries.…
Graviton Photoproduction by a Kerr-Newman Black Hole with Worldline EFT
Qinyuan Zheng
We present the first computation of the gauge-invariant, long-wavelength scattering amplitude for the graviton photoproduction by a Kerr-Newman black hole through $\mathcal{O}\big(…
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…
The NANOGrav 15 yr Data Set: Targeted Searches for Supermassive Black Hole Binaries
Nikita Agarwal, Gabriella Agazie, Akash Anumarlapudi +116
We present the first targeted searches for continuous gravitational waves (CWs) from 114 active galactic nuclei (AGN) that may host supermassive black hole binaries, using the NANO…
Unit-density SU(3) Fermi-Hubbard Model with Spin Flavor Imbalance
Zewen Zhang, Qinyuan Zheng, Eduardo Ibarra-Garcia-Padilla +2
The advent of ultracold alkaline-earth atoms in optical lattices has established a platform for investigating correlated quantum matter with SU() symmetry, offering highly tunab…
