Detecting circular polarisation in the stochastic gravitational-wave background from a first-order cosmological phase transition
John Ellis, Malcolm Fairbairn, Marek Lewicki +2
We discuss the observability of circular polarisation of the stochastic gravitational-wave background (SGWB) generated by helical turbulence following a first-order cosmological ph…

Intergalactic Magnetic Fields from First-Order Phase Transitions
John Ellis, Malcolm Fairbairn, Marek Lewicki +2
We study the generation of intergalactic magnetic fields in two models for first-order phase transitions in the early Universe that have been studied previously in connection with…

Hearing without seeing: gravitational waves from hot and cold hidden sectors
Malcolm Fairbairn, Edward Hardy, Alastair Wickens
We study the spectrum of gravitational waves produced by a first order phase transition in a hidden sector that is colder than the visible sector. In this scenario, bubbles of the…
