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) …

We present the PHANGS-MUSE survey, a programme that uses the MUSE integral field
spectrograph at the ESO VLT to map 19 massive (9.4< log (M⋆/M⊙)< 11.0) nearby (D≲ 20 …

Ionized nebulae provide critical insights into the conditions of the interstellar medium (ISM).
Their bright emission lines enable the measurement of physical properties, such as the gas …

Aims. We present the capabilities of Galapagos-2 and Galfitm in the context of fitting two-
component profiles–bulge–disk decompositions–to galaxies, with the ultimate goal of …

Dynamical models are crucial for uncovering the internal dynamics of galaxies; however,
most of the results to date assume axisymmetry, which is not representative of a significant …

ABSTRACT In Galaxy And Mass Assembly Data Release 4 (GAMA DR4), we make
available our full spectroscopic redshift sample. This includes 248 682 galaxy spectra, and …

We present a spatially resolved H ii region study of the gas-phase metallicity, ionization
parameter, and interstellar medium (ISM) pressure maps of six local star-forming and face …

Misalignments between the rotation axis of stars and gas are an indication of external
processes shaping galaxies throughout their evolution. Using observations of 3068 galaxies …

We study the alignments of galaxy spin axes with respect to cosmic web filaments as a
function of various properties of the galaxies and their constituent bulges and discs. We …
