Oct 15 2021 - 15:00 Asymptotic symmetries at spatial infinity Javier Matulich  The BMS (Bondi-van der Burg-Metzner-Sachs) group was shown long ago to be the group of asymptotic symmetries of gravity in asymptotically flat spacetime. Seminar
Oct 21 2021 - 15:00 Cosmological anomalies shedding light on the dark sector Guillermo Franco Abellan Despite the remarkable success of the ΛCDM model of cosmology, several tensions have emerged in recent years. Seminar
Oct 25 2021 - 15:00 SDSS: 20 years of cosmological results Eva Mueller I will present the cosmological implications from the final cosmological measurements of clustering using galaxies, quasars, and Lyα forests from the completed Sloan Digital Sky Survey (SDSS) linea Seminar
Oct 28 2021 - 15:00 Violations of weak cosmic censorship in black hole collisions Tomas Andrade  We simulate collisions of stable rotating black holes in six and seven dimensions. Seminar
Nov 4 2021 - 15:00 Damping of pseudo-Goldstone bosons Blaise Goutereaux When a continuous symmetry is spontaneously broken, new gapless modes appear in the spectrum, the Goldstone bosons. Seminar
Nov 8 2021 - 15:00 Gravitational waves from first-order phase transitions: A hybrid simulation, and signal enhancement from density perturbations Ryusuke Jinno Over the next few decades, we will have an exciting opportunity to detect GWs from the early Universe with space interferometers. Seminar
