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…
