Characterizing Continuous Gravitational Waves from Supermassive Black Hole Binaries in Realistic Pulsar Timing Array Data by Emiko C. Gardiner, Bence Bécsy, Luke Zoltan Kelley, Neil J. Cornish

“…Pulsar timing arrays recently found evidence for a gravitational-wave background (GWB), likely the stochastic overlap of gravitational waves from many supermassive black hole binaries. …”

Superheavy metastable strings in SO(10) by Rinku Maji, Qaisar Shafi

“…Coupled with Gμ ~ 10 −6, this metastable string network appears to provide a good fit to the recent Pulsar Timing Array data on the stochastic gravitational background. …”

Quasars Can Signpost Supermassive Black Hole Binaries by J. Andrew Casey-Clyde, Chiara M. F. Mingarelli, Jenny E. Greene, Andy D. Goulding, Siyuan Chen, Jonathan R. Trump

“…We find at 95% confidence that quasars are at most 5 times as likely to host an SMBHB as a random galaxy. Pulsar timing arrays may therefore be more likely to find SMBHBs by prioritizing quasars over a random selection of galaxies in their searches.…”

Gravitational Waves: Echoes of the Biggest Bangs Since the Big Bang and/or BSM Physics? by John Ellis

“…The gravitational waves in the nanoHz range observed by Pulsar Timing Arrays (PTAs) may have been emitted by supermassive black hole binaries, but might also have originated from BSM cosmological scenarios such as cosmic strings, or phase transitions in the early Universe. …”

Central Cluster Galaxies: A Hot Spot for Detectable Gravitational Waves from Black Hole Mergers by Yihao Zhou, Tiziana Di Matteo, Nianyi Chen, Luke Zoltan Kelley, Laura Blecha, Yueying Ni, Simeon Bird, Yanhui Yang, Rupert Croft

“…Since pulsar timing arrays (PTAs) announced the evidence for a low-frequency gravitational-wave (GW) background, continuous waves (CWs) have been the next anticipated GW signals. …”
