Global 21 cm signal: a promising probe of primordial features
Suvedha Suresh Naik, Pravabati Chingangbam, Saurabh Singh +2
Inflationary models that involve bursts of particle production generate bump-like features in the primordial power spectrum of density perturbations. These features influence the e…
Particle production during inflation: constraints expected from redshifted 21 cm observations from the epoch of reionization
Suvedha Suresh Naik, Pravabati Chingangbam, Kazuyuki Furuuchi
We examine a type of features in the primordial scalar power spectrum, namely, the bump-like feature(s) that arise as a result of burst(s) of particle production during inflation.…
Particle production during inflation: A Bayesian analysis with CMB data from Planck 2018
Suvedha Suresh Naik, Kazuyuki Furuuchi, Pravabati Chingangbam
A class of inflationary models that involve rapid bursts of particle productions predict observational signatures, such as bump-like features in the primordial scalar power spectru…
