Spectroscopic data indicate that the ionized gas in ORC4's central galaxy is shock-ionized by a wind associated with the radio ring's formation.
High-resolution MUSE observations of 30 Gaia multipeak targets confirm 19 AGN multiplets including 6 dual AGN, accounting for 22% of known close pairs below 7 kpc and showing the selection method's efficiency.
SDSS-WISE coordinate offsets plus red WISE colors pre-select advanced mergers likely to host unresolved dual-AGN candidates, with Keck AO confirming substructure in 20 of 46 targets at 43 percent yield.
N/O ratios in z~3 star-forming galaxies are indistinguishable from low-redshift values over the metallicity range 12+log(O/H)=7.5-8.44.
A homogeneous analysis of 699 spectra yields Te-Te relations for ions including N II, O II, O III, S II, S III and Ar III, with lower dispersions for relations involving Te([N II]).
The analysis identifies ~300 pc and ~200 pc transition scales in PAH emission and ISM density PDFs in nearby galaxies by decomposing JWST mid-IR images into compact and diffuse components.
Higher-resolution spectra reveal outflow signatures in ~30% of low-mass galaxies (rising to ~60% at higher SFR), with ionized mass outflow rates of 0.1-50 x 10^-3 solar masses per year.
Void galaxies show modestly higher star formation rates in early spirals and outer disks, lower extinction, and higher gas-fraction proxies than matched galaxies in filaments and walls, suggesting slower quenching in underdense environments.
M51 group shows more advanced dynamical evolution than M101, with flattened age and nebular metallicity gradients, enhanced dust, and environmental quenching signatures from interactions.
Half of strong CIII] emitters at z=5-7 show secure AGN signatures, with median equivalent width rising 0.67 dex relative to z=3-4 galaxies.
Observational analysis of COSMOS galaxy groups shows quiescent fraction builds steadily from z~1.5-2 with faster growth in richer groups, first RS ridgeline galaxies by z~2, a possible early overdensity at z=3.4, and no significant evolution in RS slope or scatter.
A multimodal neural network trained on MPA-JHU references produces SFR, stellar mass, and metallicity estimates for 547 million low-redshift galaxies in DESI LS DR10.
Spectrophotometry of 11 low-mass galaxies with extreme O32 ratios yields helium and oxygen abundances plus line-specific velocity dispersions that differ between inner and outer HII-region zones.
Barred galaxies with residual central emission and NUV-r color transition at the bar end represent an intermediate evolutionary phase in bar-driven quenching before full central quenching.
AGN activity correlates independently with bar strength and bulge prominence in z≤0.1 galaxies after controlling for mass and color.
