What if JWST’s early massive galaxies are not overestimated, but underestimated? A bottom-heavy IMF could hide tons of mass in faint stars.
Should I Stay or Should I Go? Clumps and Inward Migration
Something is missing in the middle. In JWST JADES galaxies, young clumps drop out in the inner regions, while clump structure shifts from the outskirts to the center.

Book Review: Space Hazards: Asteroids, Solar Flares and Cosmic Threats
French’s new book seperates real cosmic dangers from exaggerated ones, offering a grounded guide to the threats above our planet.
Fast metal factories at z ~ 5, lessons from ALPINE-CRISTAL-JWST
JWST reveals galaxies that built up heavy elements at record speed, reaching near-modern metallicities only a billion years after the Big Bang.
