The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
Mapping the Distant and Metal-Poor Milky Way with SDSS-V
Vedant Chandra, Phillip A. Cargile, Alexander P. Ji +28
The fifth-generation Sloan Digital Sky Survey (SDSS-V) is conducting the first all-sky low-resolution spectroscopic survey of the Milky Way's stellar halo. We describe the stellar…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
The SDSS-V Local Volume Mapper (LVM): Scientific Motivation and Project Overview
Niv Drory, Guillermo A. Blanc, Kathryn Kreckel +48
We present the Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM). The LVM is an integral-field spectroscopic survey of the Milky Way, Magellanic Clouds, and of a sample…
SDSS-V Local Volume Mapper (LVM): A Glimpse into Orion
K. Kreckel, O. V. Egorov, E. Egorova +37
The Orion Molecular Cloud complex, one of the nearest (D = 406 pc) and most extensively studied massive star-forming regions, is ideal for constraining the physics of stellar feedb…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
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 complete…
Estimating the molecular gas mass of low-redshift galaxies from a combination of mid-infrared luminosity and optical properties
Yang Gao, Ting Xiao, Cheng Li +17
We present CO(J=1-0) and/or CO(J=2-1) spectroscopy for 31 galaxies selected from the ongoing MaNGA survey, obtained with multiple telescopes. This sample is combined with CO observ…
HI-MaNGA: HI Followup for the MaNGA Survey
Karen L. Masters, David V. Stark, Zachary J. Pace +16
We present the HI-MaNGA programme of HI follow-up for the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey. MaNGA, which is part of the Fourth phase of the Sloan…
The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Overview
Kyle B. Westfall, Michele Cappellari, Matthew A. Bershady +28
Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) is acquiring integral-field spectroscopy for the largest sample of galaxies to date. By 2020, the MaNGA Survey --- one o…
SDSS-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Gail Zasowski, Hans-Walter Rix +47
SDSS-V will be an all-sky, multi-epoch spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way, trace the emergence of the chemical…
SDSS-IV MaNGA: The Spatial Distribution of Star Formation and its Dependence on Mass, Structure and Environment
Ashley Spindler, David Wake, Francesco Belfiore +9
We study the spatially resolved star formation of 1494 galaxies in the SDSSIV-MaNGA Survey. SFRs are calculated using a two-step process, using in star forming regions and $D…
The SDSS-IV MaNGA Sample: Design, Optimization, and Usage Considerations
David A. Wake, Kevin Bundy, Aleksandar M. Diamond-Stanic +15
We describe the sample design for the SDSS-IV MaNGA survey and present the final properties of the main samples along with important considerations for using these samples for scie…
