A generative latent diffusion framework jointly infers photometric-redshift PDFs and reconstructs rest-frame spectra from photometric data after pre-training a spectral autoencoder on millions of spectra.
J1248+4826 is a newly identified compact ORC candidate with a ~30 kpc ring radius and ~200 kpc total extent at assumed z=0.2, consistent with the ORC population but with the host galaxy on the ring edge and no ongoing AGN activity.
Symmetric kiloparsec-scale radio knots in NGC 7213 indicate a confined weak jet and recurrent nuclear activity in this low-luminosity AGN.
Discovery of an HI 21 cm absorber at z=0.882 towards PKS 0405-385 with associated MgII/FeII lines at the same redshift plus two other metal systems, and a revised quasar linear size >0.3 pc with no repeating intraday variability.
Stacking analysis of eROSITA observations detects statistically significant X-ray signal from hot gas out to 2 r_200m with a transition at the halo boundary, showing higher gas spread than in IllustrisTNG simulations.
JADES is a 770-hour JWST Cycle 1 survey delivering deep multi-band NIRCam imaging over ~209 arcmin² and NIRSpec spectroscopy of over 5000 sources in the GOODS-S and GOODS-N fields to study galaxy evolution from high redshift to cosmic noon.
CO(1-0) observations of three BGGs at z~0.3 yield one detection with M_H2 ~3e10 solar masses and two upper limits below 1e10, implying depletion timescales of 0.5-1.5 Gyr and possible early gas exhaustion in group environments.
KNN imputation gives highest photo-z accuracy under ideal random missingness with complete training data, while SAITS is more robust for incomplete training sets and realistic mixed missingness patterns in CSST data.
HI absorption is detected in three sight lines through two disk galaxies at 7-22 Mpc, yielding Local-Group-like spin temperatures but lower CNM fractions due to resolution averaging in emission spectra.
New sample of 377 galaxies shows MgII absorber strength rising with redshift, positive correlations with stellar mass and SFR, clumpy CGM structure, and mostly bound gas consistent with galactic fountain recycling.
FRIIs show lower cluster association rates than FRIs (30.6% vs 48.6% volume-limited; 32.6% vs 45.6% paired), with the gap widening at high luminosity, yet similar environments once inside clusters.
ELEPHANT flags hostless transients from ZTF alerts with 0.84 accuracy, confirming 67 genuine cases mostly as Type Ia supernovae from 877 candidates between 2023 and 2025.
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.
Machine learning models achieve NMAD 0.036 and 5.6% outliers for quasar photometric redshifts, identifying 185 high-probability pair candidates in MGQPC with 20 spectroscopically confirmed as physical pairs.
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.
EP250416a is an X-ray-rich long GRB at z=0.963 showing a late jet break at 1.5e6 s and optical darkness explained by A_V^host = 5.5 mag extinction.
