Gravitational waves from dark matter isocurvature
Guillem Domènech, Samuel Passaglia, Sébastien Renaux-Petel
The primordial fluctuations on large scales are adiabatic, but on smaller scales this need not be the case. Here we derive the general analytical framework to compute the stochasti…
Primordial Black Holes from CDM Isocurvature Perturbations
Samuel Passaglia, Misao Sasaki
We show that primordial black holes can be produced from the collapse of large isocurvature perturbations of the cold dark matter. We develop a novel procedure to compute the resul…
The Secret Higgstory of the Highest Temperature during Reheating
Samuel Passaglia, Wayne Hu, Andrew J. Long +1
We study the role of the Standard Model Higgs condensate, formed during cosmological inflation, in the epoch of reheating that follows. We focus on the scenario where the inflaton…
