The SDSS-V Local Volume Mapper (LVM): Technical Overview
Guillermo A. Blanc, Niv Drory, Sebastián F. Sánchez +59
The Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM) is an ultra-wide integral field spectroscopic survey of the Milky Way, the Magellanic Clouds, and a sample of gala…
Procedures for Constraining Robotic Fiber Positioning for Highly Multiplexed Spectroscopic Surveys: The Case of FPS for SDSS-V
Ilija Medan, Tom Dwelly, Kevin R. Covey +12
One crucial aspect of planning any large scale astronomical survey is constructing an observing strategy that maximizes reduced data quality. This is especially important for surve…
robostrategy: Field and Target Assignment Optimization in the Sloan Digital Sky Survey V
Michael R. Blanton, Joleen K. Carlberg, Tom Dwelly +12
We present an algorithmic method for efficiently planning a long-term, large-scale multi-object spectroscopy program. The Sloan Digital Sky Survey V (SDSS-V) Focal Plane System per…
Telescope control software and proto-model siderostat for the SDSS-V Local Volume Mapper
Hojae Ahn, Florian Briegel, Jimin Han +19
The fifth Sloan Digital Sky Survey (SDSS-V) Local Volume Mapper (LVM) is a wide-field integral field unit (IFU) survey that uses an array of four 160 mm fixed telescopes with sider…
SDSS-IV from 2014 to 2016: A Detailed Demographic Comparison over Three Years
Amy M. Jones, Rachael L. Beaton, Brian A. Cherinka +24
The Sloan Digital Sky Survey (SDSS) is one of the largest international astronomy organizations. We present demographic data based on surveys of its members from 2014, 2015 and 201…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) Spectrographs
J. C. Wilson, F. R. Hearty, M. F. Skrutskie +86
We describe the design and performance of the near-infrared (1.51--1.70 micron), fiber-fed, multi-object (300 fibers), high resolution (R = lambda/delta lambda ~ 22,500) spectrogra…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
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 o…
Marvin: A Toolkit for Streamlined Access and Visualization of the SDSS-IV MaNGA Data Set
Brian Cherinka, Brett H. Andrews, José Sánchez-Gallego +11
The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, one of three core programs of the fourth-generation Sloan Digital Sky Survey (SDSS-IV), is producing a massi…
SDSS-IV MaStar -- A Large and Comprehensive Empirical Stellar Spectral Library: First Release
Renbin Yan, Yanping Chen, Daniel Lazarz +45
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength range of 3,622-10,354A…
The Data Reduction Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey
David R. Law, Brian Cherinka, Renbin Yan +26
Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) is an optical fiber-bundle integral-field unit (IFU) spectroscopic survey that is one of three core programs in the four…
SDSS-IV/MaNGA: Spectrophotometric Calibration Technique
Renbin Yan, Christy Tremonti, Matthew A. Bershady +19
Mapping Nearby Galaxies at Apache Point Observatory (MaNGA), one of three core programs in the Sloan Digital Sky Survey-IV (SDSS-IV), is an integral-field spectroscopic (IFS) surve…
Observing Strategy for the SDSS-IV/MaNGA IFU Galaxy Survey
David R. Law, Renbin Yan, Matthew A. Bershady +11
MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is an integral-field spectroscopic survey of 10,000 nearby galaxies that is one of three core programs in the fourth-gen…
