SUMMARY:SDSS: 20 years of cosmological results - Eva Mueller (University o

DESCRIPTION:I will present the cosmological implications from the final co
 smological measurements of clustering using galaxies\, quasars\, and Lyα 
 forests from the completed Sloan Digital Sky Survey (SDSS) lineage of expe
 riments in large-scale structure. These experiments\, composed of data fro
 m SDSS\, SDSS-II\, BOSS\, and eBOSS\, offer independent measurements of ba
 ryon acoustic oscillation (BAO) measurements of angular-diameter distances
  and Hubble distances relative to the sound horizon\, rd\, from eight diff
 erent samples and six measurements of the growth rate parameter\, fσ8\, f
 rom redshift-space distortions (RSD). This composite sample is the most co
 nstraining of its kind and allows us to perform a comprehensive assessment
  of the cosmological model after two decades of dedicated spectroscopic ob
 servation. I will discuss the constraints on dark energy\, massive neutrin
 os\, and the Hubble tension. \nAdditionally\, galaxy clustering can be use
 d to constrain primordial non-Gaussianity (PNG) through the scale dependen
 t halo bias. I will present constraints on PNG from the SDSS quasar sample
 .
