Colloquium by Will Percival (Univ. Portsmouth)

Cosmological Measurements from Galaxy Clustering

Abstract:
In this talk I will review how galaxy surveys can provide cosmological information, looking towards answering the big question of “What is Dark Energy, the process driving cosmological acceleration?” I will introduce Baryon Acoustic Oscillations and Redshift-Space Distortions, two processes by which physics is encoded in the observed pattern of galaxies. I will then present recent measurements from the Baryon Oscillation Spectroscopic Survey (BOSS). I will then look ahead to future ongoing and future galaxy surveys including the extended Baryon Oscillation Spectroscopic Survey (eBOSS), Dark Energy Spectroscopic Instrument ( DESI ), and the European Space Agency Euclid satellite mission.
