Probing supermassive black hole seed scenarios with gravitational wave measurements
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
The process whereby the supermassive black holes populating the centers of galaxies have been assembled remains to be established, with the relative importance of seeds provided by…
Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary
Sven Abend, Baptiste Allard, Iván Alonso +250
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world…
What is the source of the PTA GW signal?
John Ellis, Malcolm Fairbairn, Gabriele Franciolini +7
The most conservative interpretation of the nHz stochastic gravitational wave background (SGWB) discovered by NANOGrav and other Pulsar Timing Array (PTA) Collaborations is astroph…
Cosmic Superstrings Revisited in Light of NANOGrav 15-Year Data
John Ellis, Marek Lewicki, Chunshan Lin +1
We analyze cosmic superstring models in light of NANOGrav 15-year pulsar timing data. A good fit is found for a string tension and a string intercommu…
