Axion Inflation with a Massive Abelian Gauge Field
Ricardo Z. Ferreira, Alessio Notari, José Jaime Terente Díaz
An axial coupling between an inflaton and an Abelian gauge field can trigger the tachyonic amplification of one gauge-field helicity. For a massless vector, modes with physical mom…
Biased Domain Wall Networks and their Gravitational Waves
Davide Barbini, Alessio Notari, Oriol Pujolàs +2
Cosmic Domain Wall networks are among the most interesting sources of a stochastic Gravitational Wave (GW) background from the early Universe. We present a thorough analysis of the…
Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions
Carlo Branchina, Stefania De Curtis, Luigi Delle Rose +3
Bubble-wall friction controls the dynamics of first-order cosmological phase transitions. In Boltzmann-equation approaches, a major uncertainty arises from infrared gauge bosons, w…
Mimicking Phantom Dark Energy with Evolving Dark Matter Mass
Lorenzo La Penna, Alessio Notari, Michele Redi
We present a general method to reproduce a given cosmological background through energy exchange between dark energy (DE) and dark matter (DM). This can be simply realized with a s…
The Spectrum of Gravitational Waves from Annihilating Domain Walls
Alessio Notari, Fabrizio Rompineve, Francisco Torrenti
Networks of cosmic domain walls can form in the early Universe as a consequence of the spontaneous breaking of discrete symmetries. We study the production of a cosmological backgr…
An accurate solar axions ray-tracing response of BabyIAXO
S. Ahyoune, K. Altenmueller, I. Antolin +124
BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion heliosc…
