Cosmology results from the eBOSS survey

09.10.2020 11:30 – 12:30

In this talk I present the main results of the last 20 years of BOSS $\&$ eBOSS spectroscopic observations and its cosmological interpretation. BOSS and eBOSS surveys have mapped with high precision over 2 million of galaxies and quasars spanning from low redshifts, bright nearby galaxies at $z\sim 0$, intermediate redshifts, $z \sim 0.5$, where luminous red galaxies and emission line galaxies peak, and high redshifts,$z \sim 2$, traced by quasars and Ly-alpha emission. With these observations we have been able to measure the cosmic expansion of the Universe over 11 billion years using the BAO standard ruler. Interpreting these measurements within a LCDM-like model we provide independent and competitive measurements on the amount of Dark Energy, curvature and neutrino masses.
