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.
Distant Galaxies: Dead or in Disguise?
Are some of the most massive galaxies in the early Universe truly quenched, or just hiding their star formation behind dust? Today’s bite explores how ALMA helps solve this cosmic conundrum.
Unveiling the interstellar medium of coming-of-age galaxies
…to learn more about the origins of dusty galaxies at early cosmic times.
Feed the Fire, Fade the Metals
Are cosmic clumps “homegrown”, or fueled by fresh inflow? Today’s authors find that star-forming clumps are usually more metal-poor than the disks around them.
Back for Seconds: Evidence of Two Bursts of Star Formation in an Ultra-Faint Dwarf Galaxy
Reticulum II? More like Reticulum TWO distinct periods of star formation! Or at least that’s what new spectroscopic observations incdicate.
The Oldest Starlight
What if some of JWST’s most extreme high-redshift galaxy candidates aren’t galaxies at all, but the explosive deaths of the very first stars?
