Peccei-Quinn Phase Transition at LIGO
Benedict von Harling, Alex Pomarol, Oriol Pujolas +1
The LIGO observatories can potentially detect stochastic gravitational waves arising from phase transitions which happened in the early universe at temperatures around $T\sim 10^{8…
Detuning primordial black hole dark matter with early matter domination and axion monodromy
Guillermo Ballesteros, Julián Rey, Fabrizio Rompineve
We present a scenario that ameliorates the tuning problems present in models of primordial black hole dark matter from inflation. Our setup employs the advantages of gravitational…
Oscillons and Dark Matter
Jan Olle, Oriol Pujolas, Fabrizio Rompineve
Oscillons are bound states sustained by self-interactions that appear in rather generic scalar models. They can be extremely long-lived and in the context of cosmology they have a…
