SUMMARY:Coloquio ZBA: Dr. Cristóbal Corral Badiola
DESCRIPTION:Unimodular gravity: a fresh new look into the cosmological constant problem\nDr. Cristóbal Corral Badiola\nObservational data coming from type Ia supernovae and cosmic microwave background suggest that the Universe is passing through a phase of accelerated expansion. The simplest explanation is to add the cosmological constant to Einstein’s field equations\, even though its microscopic nature is not well understood from a quantum theory viewpoint. Due to this\, different proposals have been suggested to address the late-time dynamics of the Universe\, while dispensing on the cosmological constant. In this talk\, we will review an approach suggested by Einstein himself—dubbed unimodular gravity—\, based upon a restricted diffeomorphism invariance rather than extra fields. Their cosmological consequences regarding\nthe late-time acceleration of the Universe will be highlighted. \n  \nJueves 10 de septiembre – 16:00 hrs. \n  \nSeminario On-line vía plataforma Zoom.
