Dark matter amnesia in out-of-equilibrium scenarios
Joshua Berger, Djuna Croon, Sonia El Hedri +3
Models in which the dark matter is produced at extremely low rates from the annihilation of Standard Model particles in the early Universe allow us to explain the current dark matt…
Gravitational Waves from a Pati-Salam Phase Transition
Djuna Croon, Tomás E. Gonzalo, Graham White
We analyse the gravitational wave and low energy signatures of a Pati-Salam phase transition. For a Pati-Salam scale of GeV, we find a stochastic power spectrum…
Boson Star from Repulsive Light Scalars and Gravitational Waves
Djuna Croon, JiJi Fan, Chen Sun
We study properties of boson stars consisting of ultra-light scalar dark matter with repulsive self-interactions. We investigate the origin of the maximum mass of spherically symme…
Model Discrimination in Gravitational Wave spectra from Dark Phase Transitions
Djuna Croon, Veronica Sanz, Graham White
In anticipation of upcoming gravitational wave experiments, we provide a comprehensive overview of the spectra predicted by phase transitions triggered by states from a large varie…
Exotic Gravitational Wave Signatures from Simultaneous Phase Transitions
Djuna Croon, Graham White
We demonstrate that the relic gravitational wave background from a multi-step phase transition may deviate from the simple sum of the single spectra, for phase transitions with sim…
Gravitational Radiation Background from Boson Star Binaries
Djuna Croon, Marcelo Gleiser, Sonali Mohapatra +1
We calculate the gravitational radiation background generated from boson star binaries formed in locally dense clusters with formation rate tracked by the regular star formation ra…
