Generation of gravitational waves from freely decaying turbulence
Pierre Auclair, Chiara Caprini, Daniel Cutting +4
We study the stochastic gravitational wave background (SGWB) produced by freely decaying vortical turbulence in the early Universe. We thoroughly investigate the time correlation o…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Droplet collapse during strongly supercooled transitions
Daniel Cutting, Essi Vilhonen, David J. Weir
We simulate the decay of isolated, spherically symmetric droplets in a cosmological phase transition. It has long been posited that such heated droplets of the metastable state cou…
Gravitational waves from vacuum first order phase transitions II: from thin to thick walls
Daniel Cutting, Elba Granados Escartin, Mark Hindmarsh +1
In a vacuum first-order phase transition, gravitational waves are generated from collision of bubbles of the true vacuum. The spectrum from such collisions takes the form of a brok…
Gravitational waves from vacuum first-order phase transitions: from the envelope to the lattice
Daniel Cutting, Mark Hindmarsh, David J. Weir
We conduct large scale numerical simulations of gravitational wave production at a first order vacuum phase transition. We find a power law for the gravitational wave power spectru…
