Kyle Dawson (University of Utah) "Cosmology with Spectroscopic Surveys"
The development of baryon acoustic oscillations (BAO) and redshift space distortions (RSD) as cosmological tools were one of the key accomplishments of the BOSS and eBOSS surveys in the last decade. Those measurements reach beyond redshifts z=2, offer substantial advances in our understanding of the cosmological model, and provide the core motivation for the ongoing survey with the Dark Energy Spectroscopic Instrument (DESI). When combined with other probes, these measurements provide new insights into reported tensions in the cosmological model, specifically those in the Hubble Constant and in the growth of structure. In this talk, I will present the advances of the cosmological model offered by these BAO and RSD measurements and conclude with a brief look toward the future with DESI.
About speaker: I was the Principal Investigator for the Extended Baryon Oscillation Spectroscopic Survey to constrain cosmology through the clustering of matter on scales of hundreds of millions of lightyears. In July, 2020, we released our final measurements and cosmological interpretation. A summary of this program can be found in the international press release and accompanying video. I am now the co-Spokesperson for the Dark Energy Spectroscopic Instrument (DESI). DESI will be the largest spectroscopic survey ever conducted, designed to map the cosmic distance scale and growth of structure over the last 12 billion years.
