Signals from the early Universe: a comprehensive search for primordial features in Planck CMB datasets
Antonio Raffaelli, Mario Ballardini, Nicola Barbieri
We investigate the presence of primordial oscillatory features in measurements of CMB anisotropies through a systematic comparison of phenomenological templates. Building upon prev…
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…
The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…
Current constraints on cosmological scenarios with very low reheating temperatures
Nicola Barbieri, Thejs Brinckmann, Stefano Gariazzo +3
We present a comprehensive analysis of the effects of models with very low reheating scenarios () on the cosmological observables and deri…
Refining the nonlinear modelling of primordial oscillatory features
Mario Ballardini, Nicola Barbieri
Primordial oscillatory features in the power spectrum of curvature perturbations are sensitive probes of the dynamics of the early Universe and can provide insights beyond the stan…
