Red quasars are intrinsically X-ray weak with low alpha_OX values, tracing a distinct evolutionary stage of suppressed black hole accretion relative to stellar mass growth.
In 37 massive ETGs, the IMF becomes less bottom-heavy with radius, with average α_IMF falling from 2.16 to 1.74 and IMF gradients dominating M/L variations over stellar population effects.
At fixed stellar mass, inner gas mass—not size, SFR, or potential—best predicts gas metallicity, and differences in long-term inflow histories can explain the pattern.
Balmer decrements in CV spectra form a diagnostic diagram that separates period-bouncers from pre-bounce systems via fitted logistic regression.
Reprojects abundances of 199k stars into 4 patterns, identifying enrichment pathways with strong chemo-spatial, age, and vertical correlations plus a transition at ~6 Gyr.
DESI's instrumentation, including a 3.2-degree prime-focus corrector, 5020 fiber positioners across ten petals, and ten three-channel spectrographs, has been successfully installed and meets all performance goals for a five-year survey of 40 million galaxies and quasars.
LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.
Spirals in spiral-elliptical pairs have centrally suppressed star formation and elevated gas-phase metallicity, unlike spirals in spiral-spiral pairs, with strength set by companion mass and gas kinematics.
Void galaxies identified by local volume in non-spherical voids are bluer and more star-forming than non-void galaxies, with the environmental effect decreasing with stellar mass.
DESI K-giant catalog identifies Aleph, Sagittarius, GSE, Cetus-Palca and Orphan-Chenab, then shows residual halo high-angular-momentum stars have bimodal MDFs unlike GSE or Sagittarius.
Disk reflection from a compact lamp-post corona explains the X-ray polarization and spectra of NGC 4151.
A blind 12D chemo-dynamical clustering analysis with UMAP and HDBSCAN on SDSS-V DR19 and Gaia DR3 data recovers seven known halo substructures and reports five new tightly bound candidates FO1-FO5.
New CO observations of low-mass late-type galaxies show the molecular gas-star formation relation remains linear, with shorter depletion times and a shift toward molecular-dominated gas at higher stellar masses.
Observational study finds spiral structure correlates with steeper metallicity gradients, larger bulges with shallower gradients and higher metallicities, but no gradient differences from bars or spiral winding tightness.
MaNGA-based comparison shows AGN-PSBs likely evolve from RPSBs with lower merger fractions than high-mass CPSBs, indicating AGN feedback is not necessary for post-starburst formation.
Ages inferred for red giant stars via machine learning are generally insensitive to hyperparameters and architecture but somewhat sensitive to training set choice, especially for the oldest, coolest, and lowest-metallicity stars.
Multi-wavelength observations of 4C+29.30 show a misaligned biconical ionized outflow and localized jet-ISM interactions, providing evidence for simultaneous radiative and mechanical AGN feedback.
MUST is a new 6.5 m telescope designed to deliver simultaneous optical spectra for over 20,000 targets across a 5 deg² field, enabling the largest 3D spectroscopic map of the Universe with redshifts for more than 100 million objects over an 8-year survey.
Cool gas inflows occur in ~70% of red geyser galaxies at median 47 km/s, with reservoirs 7 times larger in radio-detected systems and 2.7 times larger in interacting ones, linking galaxy environment to AGN fueling and quiescence regulation.
C/N/O abundance patterns indicate that some α-rich young red giants are merger or mass-transfer products rather than genuinely young stars with anomalous chemistry.
