JWST and ALMA data provide the earliest direct evidence of ram-pressure stripping in a post-starburst galaxy at z=3.06, implying the process can quench star formation in nascent groups at z>3.
Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.
The UV luminosity function at z~7 rises steeply with slope alpha=-1.98 to M_UV=-12.3 with no turnover, indicating faint galaxies dominate the ionizing photon budget during reionization.
Bright globular clusters in Abell 2744 trace the three main mass clumps and match weak-lensing mass maps more closely than other galactic components, using a Poisson point process model.
Joint lensing-kinematics analysis of nine CLASH clusters constrains chameleon gravity, yielding GR-consistent bounds for NFW and Hernquist profiles and |f_R| ≲ 2-5×10^{-5} for f(R) models.
An updated strong lensing model of SDSSJ1110+6459 using JWST-resolved clumps yields M(<250 kpc) = 1.21^{+0.09}_{-0.04} imes 10^{14} M_/sun, heta_E = 10.8^{+0.3}_{-0.4} arcsec, and \mu_tot = 24.2^{+3.4}_{-1.2} with 2-8 imes better magnification precision than prior models.
Presents strong lensing models and mass measurements for 14 clusters (z=0.25-1.06) based on JWST data, with new lensed systems and public data release.
