TransitionListener v2.0 -- Robust gravitational wave predictions for cosmological phase transitions
Jonas Matuszak, Carlo Tasillo
Gravitational wave backgrounds from strong first-order cosmological phase transitions are key observational targets predicted by many SM extensions and might be observed by current…
Tuning the violins: dark sector phase transition models for the PTA signal
Torsten Bringmann, Thomas Konstandin, Jonas Matuszak +2
First-order phase transitions in a dark sector have been invoked as an intriguing possibility to explain the observed stochastic gravitational wave background at nanohertz frequenc…
Sub-GeV dark matter and nano-Hertz gravitational waves from a classically conformal dark sector
Sowmiya Balan, Torsten Bringmann, Felix Kahlhoefer +2
Strong first-order phase transitions in a dark sector offer a compelling explanation for the stochastic gravitational wave background in the nano-Hertz range recently detected by p…
Signals of merging supermassive primordial black holes in pulsar timing arrays
Paul Frederik Depta, Kai Schmidt-Hoberg, Pedro Schwaller +1
In this work we evaluate whether the gravitational wave background recently observed by a number of different pulsar timing arrays could be due to merging primordial supermassive b…
