DES supernova data alone give Omega_M = 0.352 +/- 0.017 in flat LambdaCDM and confirm acceleration at >5 sigma, with dark energy consistent with a cosmological constant to within ~2 sigma when combined with other probes.
Euclid identifies 16 massive compact galaxies with V-shaped SEDs at z>4, half as old as the universe at their redshift, mostly distinct from known AGN.
FUV imaging shows ongoing massive star formation in the extended low-density outskirts of NGC2090, with smaller complexes, rising specific SFR, and flux ratios consistent with a top-heavy IMF.
Strong blended Lyα absorbers cluster with Lyα emitting galaxies at z>3 within 300 kpc and 300 km/s, confirming they trace the circumgalactic medium interface.
A catalog of 6104 high-redshift quasar candidates (4.5 < z < 7) in the southern hemisphere was produced via multiwavelength photometry and SED fitting, with spectroscopic confirmation of three objects at z > 5.
New adaptive optics data from nine LIRGs yields undetectable CCSN fractions of 88% for optical and 61% for near-IR surveys when combined with prior results.
Transfer learning with a Zoobot CNN on SDSS DR18 data identifies 3,679 lopsided spiral galaxies at 87% test accuracy, with lopsided systems showing higher star formation, bluer colors, lower mass and concentration.
