Stochastic gravitational wave (GW) backgrounds from first-order phase transitions are an exciting target for future GW observatories and may enable us to study dark sectors with very weak couplings to the Standard Model. In this work we show that such signals may be significantly enhanced for hot dark sectors with a temperature larger than the one of the SM thermal bath. The need to transfer the entropy from the dark sector to the SM after the phase transition can however lead to a substantial… Expand


Gravitational Waves from a Dark Phase Transition.
The gravitational wave signal provides a unique test of the gravitational interactions of a dark sector, and the complementarity with conventional searches for new dark sectors is discussed, as well as symmetric and asymmetric composite dark matter scenarios. Expand
Dark, cold, and noisy: constraining secluded hidden sectors with gravitational waves
We explore gravitational wave signals arising from first-order phase transitions occurring in a secluded hidden sector, allowing for the possibility that the hidden sector may have a differentExpand
Dynamic freeze-in: impact of thermal masses and cosmological phase transitions on dark matter production
A bstractThe cosmological abundance of dark matter can be significantly influenced by the temperature dependence of particle masses and vacuum expectation values. We illustrate this point in threeExpand
A fresh look at the gravitational-wave signal from cosmological phase transitions
Many models of physics beyond the Standard Model predict a strong first-order phase transition (SFOPT) in the early Universe that leads to observable gravitational waves (GWs). In this paper, weExpand
Light Dark Matter from Entropy Dilution
We show that a thermal relic which decouples from the standard model (SM) plasma while relativistic can be a viable dark matter (DM) candidate, if the decoupling is followed by a period of entropyExpand
Hearing without seeing: gravitational waves from hot and cold hidden sectors
A bstractWe 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 hiddenExpand
Thermal dark matter from a highly decoupled sector
It has recently been shown that if the dark matter is in thermal equilibrium with a sector that is highly decoupled from the Standard Model, it can freeze-out with an acceptable relic abundance, evenExpand
Superheavy thermal dark matter and primordial asymmetries
A bstractThe early universe could feature multiple reheating events, leading to jumps in the visible sector entropy density that dilute both particle asymmetries and the number density of frozen-outExpand
Dark Matter production from relativistic bubble walls
In this paper we present a novel mechanism for producing the observed Dark Matter (DM) relic abundance during the First Order Phase Transition (FOPT) in the early universe. We show that the bubbleExpand
Cannibal dark matter and large scale structure
Cannibals are dark matter particles with a scattering process that allows three particles to annihilate to two. This exothermic process keeps the gas of the remaining particles warm long after theyExpand
