Warm Inflation and Gravitational Wave Signatures in Cosmology

Explore a 48-minute lecture on warm inflation and gravitational waves delivered at the International Centre for Theoretical Sciences as part of the program "Hearing beyond the standard model with cosmic sources of Gravitational Waves." Delve into the intersection of warm inflation theory and gravitational wave physics, examining how these phenomena contribute to our understanding of the early universe. Learn about the detection of gravitational waves from various cosmological sources, including astrophysical mergers, tensor perturbations during inflation, and stochastic gravitational wave backgrounds. Understand the implications of recent discoveries by collaborations like NANO-Grav and InPTA, and examine how gravitational wave signals can probe physics beyond the Standard Model and potential modifications to general relativity. Gain insights from expert speaker Mar Bastero-gil in this specialized physics lecture that bridges particle physics, cosmology, and gravitational wave astronomy.
