A new RTU grid method models the lensing source as a Gaussian process on a ray-transformed uniform grid, achieving comparable fits with roughly half the pixels per dimension and higher ELBOs on mock data.

First narrow-line flux ratios for lensed quasar RXJ1131-1231 measured with JWST/NIRSpec IFS at ~5% precision, detecting cusp anomaly consistent with prior work.
Bayesian photometric cosmic chronometer analysis on VIPERS PDR2 data yields H(z=0.65)=93.68±28.27(stat)±10.67(syst) km/s/Mpc, consistent with spectroscopic CC results and Planck ΛCDM, as a proof of concept for photometric surveys.
New H0 = 67.0 +9.3/-7.8 km/s/Mpc from joint lens-model fit to time delays of SN Requiem and SN Encore in MACS J0138.0-2155.
