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…

Knot reconstruction of the scalar primordial power spectrum with Planck, ACT, and SPT CMB data
Antonio Raffaelli, Mario Ballardini
We investigate a non-parametric Bayesian method for reconstructing the primordial power spectrum (PPS) of scalar perturbations using temperature and polarisation data from the {\em…

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…
