Abstract The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is
currently acquiring integral-field spectroscopy for the largest sample of galaxies to date. By …

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 …

The Sloan Digital Sky Surveys (SDSS) have been almost continuously observing the skies
for over 20 yr, since the project began with a first phase in 1998 (SDSS-I; York et al. 2000) …

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 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 …

We investigate how star formation quenching proceeds within central and satellite galaxies
using spatially resolved spectroscopy from the SDSS-IV MaNGA DR15. We adopt a …

ABSTRACT We present the MaNGA PyMorph photometric Value Added Catalogue (MPP-
VAC-DR17) and the MaNGA Deep Learning Morphological VAC (MDLM-VAC-DR17) for the …

The Sloan Digital Sky Survey (SDSS) has been observing the universe using the 2.5 m
Sloan Foundation Telescope (Gunn et al. 2006) at Apache Point Observatory (APO) for over …

We describe the 2023 release of the spectral synthesis code Cloudy. Since the previous
major release, migrations of our online services motivated us to adopt git as our version …

We study the gas phase metallicity (O/H) and nitrogen abundance gradients traced by star-
forming regions in a representative sample of 550 nearby galaxies in the stellar mass range …
