Webinar《Cosmological tensions》

Cosmological tensions

After introducing the standard model of cosmology and its parameters, the speaker will discuss two important tensions between early and late-time measurements, namely the H0 tension and the sigma8 tension. Considering a small late-time deviation of the standard model, the speaker will drive fully analytical conditions that any late-time dark energy model has to satisfy in order to solve both tensions simultaneously(see arxiv:2201.11623).

“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.
