Description
Understanding the physics of the early Universe remains one of the central goals of modern cosmology. While the inflationary paradigm provides a compelling mechanism for generating primordial perturbations, most observational constraints to date rely on the slow-roll approximation and specific model assumptions. In this talk, I present a model-agnostic approach to probing inflationary dynamics beyond the slow-roll regime, leveraging the latest observations from the cosmic microwave background (CMB) and large-scale structure (LSS).
By relaxing standard assumptions and allowing for more general departures from canonical evolution, we explore a broader class of inflationary scenarios and their imprints on cosmological observables. This framework enables a systematic search for signatures of non-trivial dynamics in the primordial Universe, including features that may be inaccessible within conventional parametrizations.
Combining multiple cosmological probes, we demonstrate how current data can be used to place robust, assumption-light constraints on the inflationary epoch. These results open new avenues for testing the fundamental physics driving cosmic inflation and highlight the growing synergy between early- and late-time observables in precision cosmology.
