[Guest] The Walking Red: Why are you so quiet and overdense?
Why do we see so many massive, dead galaxies at early cosmic times? Guest author Tatevik Mkrtchyan illuminates a slice of the cosmic graveyard!
A Possible GLIMPSE of the Universe’s First Stars
Today’s bite explores a new method to find the galaxies hosting the Universe’s first generation of stars
She’s Not Like the Other Galaxies: The Nearly-Impossible Qualities of CEERS2-588
Galaxy-modelers beware! Today’s bite will guide you through an analysis of CEERS2-588, a quirky, UV-luminous, early galaxy discovered by JWST that’s causing issues in our theoretical models!
Do we actually know how old the Universe is?
So we have a pretty good idea of how old the Universe is right? Well according to JWST data, maybe not? Rest assured, today’s bite gets to the bottom of the debate.
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.
