Introduces 9 synthetic annotation tasks and benchmarks for behavioral cloning, finding hierarchical skill learning, scaling benefits, effective multi-task pretraining, and shared internal representations of task phases and mistakes.
SHAMe-SF modeling of small-scale DESI ELG clustering delivers 6% precision on σ8 and Ωm h², matching full DR1 results with 1% volume.
FRB dispersion measures directly constrain suppression of the matter power spectrum due to feedback at k ~ 0.1-3 h/Mpc, reduce posterior variance by a factor of ~8 at k~1 h/Mpc, and exclude extreme large-scale feedback scenarios at ~2 sigma.
Cluster environments accelerate stellar halo growth in massive quiescent galaxies but suppress it in the lowest-mass ones, based on stacked surface-brightness profiles of ~96,000 galaxies at 0.1<z<1.
Cool galactic outflows seen in stacked DESI spectra can escape low-mass galaxy halos, providing indirect evidence that stellar feedback drives their baryon deficiency.
TNG50 simulation analysis finds early-forming halos show higher stellar mass, metallicity, lower CGM gas mass and sSFR at z=0, with mass-dependent CGM metallicity reversal and cold-gas kinematics differences.
A large collaboration compiles and compares merger rate predictions for massive black holes across multiple galaxy formation models to forecast LISA detections and quantify uncertainties.
Simulated likelihood analysis shows Limber approximation, neglected RSD, and approximate nonlinear power spectra each induce cosmological biases of ~1 sigma or more (exceeding 2 sigma for Rubin) in Roman and Rubin 3x2pt studies.
Stellar population synthesis of three AGN hosts shows recent rejuvenation and central metallicity drops consistent with gas inflows fueling both star formation and AGN activity.
Review of HI gas studies, cosmic web processes, and SKA's role in advancing the field through high-sensitivity surveys.
