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 accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

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 the cosmological implications from final measurements of clustering using
galaxies, quasars, and Ly α forests from the completed Sloan Digital Sky Survey (SDSS) …

The spectral analysis and data products in Data Release 16 (DR16; 2019 December) from
the high-resolution near-infrared Apache Point Observatory Galactic Evolution Experiment …

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 …

It is now 16 years since the first data release from the Sloan Digital Sky Survey (SDSS; York
et al. 2000). This Early Data Release, or EDR, occurred in 2001 June (Stoughton et al …

We create a sample of spectroscopically identified galaxies with z< 0.2 from the Sloan
Digital Sky Survey (SDSS) Data Release 7 (DR7), covering 6813 deg2. Galaxies are chosen …

We present an overview of a new integral field spectroscopic survey called MaNGA
(Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the …

ABSTRACT The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure
the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger …
