The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

Bela Abolfathi, +364 more
- 19 Apr 2018 - 
TL;DR: SDSS-IV is the fourth generation of the Sloan Digital Sky Survey and has been in operation since 2014 July. as discussed by the authors describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14).
Journal ArticleDOI

The SDSS-IV extended baryon oscillation spectroscopic survey: Overview and early data

Kyle S. Dawson, +158 more
- 04 Feb 2016 - 
TL;DR: The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) as mentioned in this paper uses four different tracers of the underlying matter density field to expand the volume covered by BOSS and map the large-scale structures over the relatively unconstrained redshift range 0.6 0.87.

Franco D. Albareti, +336 more
- 05 Aug 2016 - 
TL;DR: Data Release 13 (DR13) as mentioned in this paper is the first data release from SDSS-IV, which contains new data, reanalysis of existing data sets and, like all SDSs data releases, is inclusive of previously released data.

The 13th Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey Mapping Nearby Galaxies at Apache Point Observatory

Franco D. Albareti, +400 more
- 08 Dec 2017 - 
TL;DR: Data Release 13 (DR13) as discussed by the authors provides the first 1390 spatially resolved integral field unit observations of nearby galaxies from the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2), Mapping Nearby Galaxies at APO (MaNGA), and the Extended Baryon Oscillation Spectroscopic Survey (eBOSS).
