A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
LEGGOS presents a uniform framework that jointly models lensing, photometry, and integral-field spectroscopy to disentangle stellar populations in clumps of high-redshift lensed galaxies.
Reports a catalog of 519 cluster candidates (74 at z>1.5) from VIDEO fields via AMICO and WaZP, shows red-sequence galaxies consistent with passive evolution since high redshift, and evaluates MOONRISE detection strategies up to z~1.7.
Optical spectroscopy is required to unlock the full potential of SKAO extragalactic surveys through precise redshifts, activity diagnostics, HI stacking, and large-scale structure mapping.
