In a six-year program started in 2014 July, the Extended Baryon Oscillation Spectroscopic
Survey (eBOSS) will conduct novel cosmological observations using the BOSS …

The ordering of the neutrino masses is a crucial input for a deep understanding of flavor
physics, and its determination may provide the key to establish the relationship among the …

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky
Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the …

We present a full Λ CDM analysis of the BOSS DR12 dataset, including information from the
power spectrum multipoles, the real-space power spectrum, the reconstructed power …

We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman-α (Lyα)
forest of high-redshift quasars with the first-year dataset of the Dark Energy Spectroscopic …

We present the cosmological implications from final measurements of clustering using
