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) …

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 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 …

Context. Galaxy mergers and interactions are an important process within the context of
galaxy evolution, however, there is still no definitive method which identifies pure and …

The Galaxy Zoo project has provided quantitative visual morphologies for over a million
galaxies, and has been part of a reinvigoration of interest in the morphologies of galaxies …

The morphological diversity of galaxies is a relevant probe of galaxy evolution and
cosmological structure formation, but the classification of galaxies in large sky surveys is …

Mergers play a complex role in galaxy formation and evolution. Continuing to improve our
understanding of these systems requires ever larger samples, which can be difficult (even …

Multicomponent modeling of galaxies is a valuable tool in the effort to quantitatively
understand galaxy evolution, yet the use of the technique is plagued by issues of …

Context. The galaxy population in the contemporary Universe is characterised by a clear
bimodality, blue galaxies with significant ongoing star formation and red galaxies with only a …
