SED Fitting: How Astronomers Understand Galaxies Across Time
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?
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.
