Can supercooled phase transitions explain the gravitational wave background observed by pulsar timing arrays?
Peter Athron, Andrew Fowlie, Chih-Ting Lu +4
Several pulsar timing array collaborations recently reported evidence of a stochastic gravitational wave background (SGWB) at nHz frequencies. Whilst the SGWB could originate from…
