The distribution of post-starburst regions within galaxies is linked to diverse quenching pathways that are likely driven by mergers. Guest author, Emmy Wisz, explains how different star formation histories could be the key to understanding quenching mechanisms.

Why do we see so many massive, dead galaxies at early cosmic times? Guest author Tatevik Mkrtchyan illuminates a slice of the cosmic graveyard!
Compact ultra-faint systems? More like confusing ultra-faint systems!
When studying distant galaxies, SED fitting is one tool to rule them all. But how can we learn the detailed history of entire galaxies from just a few snapshots?
Today we interview Dr. Adam Burgasser, professor of astronomy and astrophysics at the University of California San Diego (UCSD), and a plenary speaker at #AAS247
In the latest of our #UndergradResearch series, discover how to estimate the metallicities of early galaxies using line ratios from JWST with Vidit Bhandari.
