JWST spectra reveal that two z~7 galaxies already show near-solar iron-to-silicon ratios with no strong odd-even effect, favoring early Type Ia supernovae over pair-instability supernovae as the source of iron enrichment.

SAMOS demonstrates reliable target acquisition, programmable multi-object spectroscopy at R~2500 and R~10000, and 0.3 Å calibration accuracy after on-sky commissioning at SOAR.
Three anomalous microlensing events are re-modeled as binary-lens binary-source (2L2S) systems that resolve prior residuals, with source stars identified as G8V/M3V, G8V/K2V, and G6V/G8V pairs and lenses inferred as low-mass binaries via Bayesian methods.
Three new planets detected via 2023 KMTNet microlensing with mass ratios log q ~ -1.9, -2.0, -2.6; overall 2023 sample of 25 planets matches prior mass-ratio distribution.
Analyses of ten microlensing events identify candidate brown dwarf companions in binary systems, with two events suggesting brown dwarf binaries.
