This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band photometric data for 180 million objects selected over 6670 deg^2, and 673,280 spectra of galaxies, quasars, and stars selected from 4783 deg^2 of that imaging data using the standard SDSS target selection algorithms. These numbers represent a roughly 25% increment over those of the Third Data Release. The Fourth Data Release also includes an additional 131,840 spectra of objects selected using a variety of alternative algorithms, to address scientific issues ranging from the kinematics of stars in the Milky Way thick disk to populations of faint galaxies and quasars.

  1. What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    No current simulation simultaneously reproduces observed halo hot-gas fractions and local galaxy star-formation/quenching demographics; strong AGN feedback overquenches, weak feedback retains too much gas.

  2. A search for HI absorption in distant star-forming galaxies with ASKAP-FLASH - II. Direct observations and stacking of 21 cm line

    astro-ph.GA 2026-07 conditional novelty 5.5 of 10

    One new associated HI 21 cm absorber is found at z=0.863; ordered stacking of associated non-detections yields only bootstrap-unsupported tentative features that vanish as fainter sources raise optical-depth noise, wh...

  3. Optically Selected Superthin Galaxies Remain Thin in the Near-infrared

    astro-ph.GA 2026-07 conditional novelty 5.0 of 10

    Optically selected superthin galaxies remain superthin in NIR with unchanged axis ratios, showing no prominent thick disk from old stars, and prefer lower-density environments consistent with high-halo-spin formation.
