Probing dark energy and inflation with gravitational waves

Webinar:- Probing dark energy and inflation with gravitational waves

In this talk, the speaker will summarize several recent results about gravitational wave cosmology in the context of dark energy and inflation. In the first part of the talk, he will concentrate on astrophysical gravitational waves and will argue that the spatial clustering of gravitational wave sources provides a wealth of invaluable information concerning the propagation law of gravitational waves. He will demonstrate its importance for constraining deviations from General Relativity on cosmological scales. In the second part of the talk, the speaker will discuss gravitational waves produced during inflation and will revisit the implications of their possible near-future detection for inflationary models. He will particularly present our proposal of resonant gravitational wave production during inflation due to non-linear effects and will discuss the implications for the well-known Lyth bound. He will also present related ideas for producing induced gravitational waves and primordial black holes on small scales.

“Copernicus Webinar and Colloquium Series”: To promote scientific discussions during this pandemic, they are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.
