Forever Alone: A Black Hole Destined to Stay too Big
This ancient black hole is far too massive for its galaxy. Thirteen billion years later, it might still be haunting us.
UR: Data-Driven Analysis of Galactical Evolution
In the latest of our #UndergradResearch series, discover how to estimate the metallicities of early galaxies using line ratios from JWST with Vidit Bhandari.
Black Holes Reveal their Seeds
Astronomers have spent decades searching for seeds of the earliest black holes. Did JWST just glimpse the very first ones?
Astronomers Hate Them! This Star Formation Ingredient Makes Clusters Look 300 Million Years Older
Like a bouncer at a nightclub, JWST is trying to figure out if some star clusters are really as old as they say they are …
Dust in the Wind: A New Tool for Understanding Galactic Outflows
The galaxy M82 is host to an extended multiphase wind driven by star formation. Today’s paper attempts to use JWST observations of dust in the wind to understand the structure of its cooler gas.
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.
