Gravitational scalar production with a generic reheating scenario
Francesco Costa, Jinsu Kim
Gravitational production of decoupled scalars during inflationary and post-inflationary phases is efficient and can lead to over-production. We study this production with various r…
ELENA: a software for fast and precise computation of first order phase transitions and gravitational waves production in particle physics models
Francesco Costa, Jaime Hoefken Zink, Michele Lucente +2
We present ELENA (EvaLuator of tunnElliNg Actions), an open-source Python package designed to compute the full evolution of first-order phase transitions in the early Universe gene…
From oversimplified to overlooked: the case for exploring Rich Dark Sectors
Asli Abdullahi, Francesco Costa, Andrea Giovanni De Marchi +9
The Standard Model (SM) of particle physics provides a very successful description of fundamental particles and their interactions but it is incomplete, as neutrino masses, dark ma…
Supercooled Dark Scalar Phase Transitions explanation of NANOGrav data
Francesco Costa, Jaime Hoefken Zink, Michele Lucente +2
The evidence of a Stochastic Gravitational Wave Background (SGWB) in the nHz frequency range is posed to open a new window on the Universe. A preferred explanation relies on a supe…
