The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in 2014 July. It pursues three core programs: the Apache Point Observatory Galactic Evolution Experiment 2…
The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra
- Romina Ahumada, C. Prieto, H. Zou
- Physics
- 5 December 2019
This paper documents the sixteenth data release (DR16) from the Sloan Digital Sky Surveys; the fourth and penultimate from the fourth phase (SDSS-IV). This will be the first release of data from the…
Estimating the H i gas fractions of galaxies in the local Universe
We use a sample of 800 galaxies with H I mass measurements from the HyperLeda catalogue and optical photometry from the fourth data release of the Sloan Digital Sky Survey (SDSS) to calibrate a new…
The SDSS-IV extended baryon oscillation spectroscopic survey: Overview and early data
In a six-year program started in 2014 July, the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will conduct novel cosmological observations using the BOSS spectrograph at Apache Point…

- PhysicsThe Astrophysical Journal Supplement Series
- 6 December 2018
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years of operation (2014…
Type IIn Supernova SN 2010jl: Optical Observations for over 500 Days after Explosion
- Tianmeng Zhang, Xiaofeng Wang, Jun Ma
- Physics
- 30 August 2012
We present extensive optical observations of a Type IIn supernova (SN IIn) 2010jl for the first 1.5 years after its discovery. The UBVRI light curves demonstrated an interesting two-stage evolution…
The extended Baryon Oscillation Spectroscopic Survey: a cosmological forecast
- Gong-Bo Zhao, Yuting Wang, H. Zou
- Physics
- 28 October 2015
We present a science forecast for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) survey. Focusing on discrete tracers, we forecast the expected accuracy of the baryonic acoustic…
