Title: Cosmological Implications from two Decades of Spectroscopic Surveys at the Apache Point observatory and Expectations for the Next Decade

 

Abstract: The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) concluded observations of the cosmic distance scale and the growth of structure in February, 2019. The three-dimensional clustering in all samples from the Sloan Digital Sky Survey (SDSS) was used to make 15 distinct, high precision measurements of Baryon Acoustic Oscillations (BAO) to an effective redshift z<2.4 and six measurements of redshift space distortions (RSD) to z<1.5. Using available cosmological samples, we provide new constraints on the cosmological model with an emphasis on the role of the SDSS BAO and RSD clustering measurements in advancing the cosmological model. In this talk, I will give a brief overview of these BAO and RSD measurements, highlight the advances in modeling the cosmological model, and provide a look ahead to what we are expecting from the Dark Energy Spectroscopic Instrument (DESI).
