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~0, intermediate redshifts, z~0.5, where luminous red galaxies and emission line galaxies peak, and high redshifts, z~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.
