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…

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.…

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…
