Dear all, This week we have the pleasure of hosting Prof. Héctor Gil Marín from the University of Barcelona, who will present the latest results from the DESI experiment. The seminar will take place in the J. Sacton Room this Friday, March 6th, at 2:00 PM. Please find further details below: **************************************** Title: Latest results from DESI and their implication in cosmology Abstract: The Dark Energy Spectroscopy Instrument (DESI) has undertaken the largest spectroscopic survey to date. I will briefly describe the instrument and present the recently released results in terms of the Baryon Acoustic Oscillations (BAO) and Full-Shape analyses. Thanks to these studies, we have been able to measure the expansion history of the universe with unprecedented precision, test the theory of gravity at cosmological scales, and set an upper limit on the sum of the effective masses of neutrinos. When combining with other datasets such as the CMB or SNe samples, interesting findings point towards the possibility of the existence of a type of Dark Energy that would evolve with time.
