Large surveys of the angular positions and redshifts of galaxies provide a wealth of cosmological information about the late-time Universe and its accelerating expansion. In this seminar I will review the physical mechanisms that encode this information in the observed clustering of galaxies, and present recent results from the Baryon Oscillation Spectroscopic Survey (BOSS). I will then look ahead to future surveys including the Dark Energy Spectroscopic Instrument (DESI) and the ESA Euclid satellite mission, showing how they will revolutionise our understanding of cosmic acceleration.
