PhaseTracer2: from the effective potential to gravitational waves
Peter Athron, Csaba Balazs, Andrew Fowlie +4
In recent years, the prospect of detecting gravitational waves sourced from a strongly first-order cosmological phase transition has emerged as one of the most exciting frontiers o…
How robust are gravitational wave predictions from cosmological phase transitions?
Peter Athron, Lachlan Morris, Zhongxiu Xu
Gravitational wave (GW) predictions of cosmological phase transitions are almost invariably evaluated at either the nucleation or percolation temperature. We investigate the effect…
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…
Cosmological phase transitions: from perturbative particle physics to gravitational waves
Peter Athron, Csaba Balázs, Andrew Fowlie +2
Gravitational waves (GWs) were recently detected for the first time. This revolutionary discovery opens a new way of learning about particle physics through GWs from first-order ph…
Supercool subtleties of cosmological phase transitions
Peter Athron, Csaba Balázs, Lachlan Morris
We investigate rarely explored details of supercooled cosmological first-order phase transitions at the electroweak scale, which may lead to strong gravitational wave signals or ex…
How arbitrary are perturbative calculations of the electroweak phase transition?
Peter Athron, Csaba Balazs, Andrew Fowlie +3
We investigate the extent to which perturbative calculations of the electroweak phase transition are arbitrary and uncertain, owing to their gauge, renormalisation scale and scheme…
