Theoretical Physics – From Outer Space to Plasma

Cosmic acceleration revealed by Type la supernovae?

41 min • 1 november 2019

In this talk Subir Sarkar will explain how deflagration supernovae have been used to infer that the Hubble expansion rate is accelerating, and critically assess whether the acceleration is real and due to `dark energy’.
