Beyond thermal approximations: Precise cosmological bounds on Axion-Like Particles
Nicola Barbieri, Luca Caloni, Martina Gerbino +2
We derive updated cosmological bounds on light axion-like particles (ALPs) coupled to leptons or photons, using a full phase-space treatment of their production from the primordial…
Cosmic strings and domain walls: the impact of CMB -mode data
Luca Caloni, Ricardo Z. Ferreira, Lara Sousa +1
We analyse CMB constraints on stable networks of cosmic strings and domain walls using for the first time full Planck 2018 data together with BICEP/Keck 2018 -mode measurements.…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Constraining UV freeze-in of light relics with current and next-generation CMB observations
Luca Caloni, Patrick Stengel, Massimiliano Lattanzi +1
Cosmological observations allow to measure the abundance of light relics produced in the early Universe. Most studies focus on the thermal freeze-out scenario, yet light relics pro…
Echoes from a long time ago: Chewbacca inflation
D. Sidious, S. Arcari, N. Barbieri +9
The cosmic microwave background (CMB) radiation offers a unique avenue for exploring the early Universe's dynamics and evolution. In this paper, we delve into the fascinating realm…
Probing Lorentz-violating electrodynamics with CMB polarization
Luca Caloni, Serena Giardiello, Margherita Lembo +4
We perform a comprehensive study of the signatures of Lorentz violation in electrodynamics on the Cosmic Microwave Background (CMB) anisotropies. In the framework of the minimal St…
Novel cosmological bounds on thermally-produced axion-like particles
Luca Caloni, Martina Gerbino, Massimiliano Lattanzi +1
We constrain the coupling of thermally-produced axion-like particles (here axions) with photons and gluons, using data from the cosmic microwave background (CMB) spectra and baryon…
Updated cosmological constraints on Macroscopic Dark Matter
Luca Caloni, Martina Gerbino, Massimiliano Lattanzi
We revise the cosmological phenomenology of Macroscopic Dark Matter (MDM) candidates, also commonly dubbed as Macros. A possible signature of MDM is the capture of baryons from the…
Tensor non-Gaussianity in chiral scalar-tensor theories of gravity
Nicola Bartolo, Luca Caloni, Giorgio Orlando +1
Violation of parity symmetry in the gravitational sector, which manifests into unequal left and right circular polarization states of primordial gravitational waves, represents a w…
