Star Formation Acceleration
Today’s paper discusses a new way to measure physical properties of galaxies—including, for the first time, “star formation acceleration.”
2 slow, 2 furious
Massive elliptical galaxies come in two types, the fast and the furious (or, more formally, fast rotators and slow rotators). But what’s the difference? And why is there a difference? In today’s article we’ll look at the work of two independent teams working on the same problem.
Live fast, die young: quiescent galaxies in the early universe
A newly discovered quiescent galaxy in the early universe strains our understanding of galaxy evolution
From One Satellite to Another: Finding Clusters with Gaia
2 new globular clusters detected by Gaia, and what we know about them.
The largest, ugliest duckling in the universe.
So much of our universe is stunningly beautiful. Let’s spend a little time on something that isn’t, and follow the journey from stunning spiral galaxies to plain old giant ellipticals.
Bulges are red, disks are blue…
…or are they? The color-mass diagram for galaxies can tell us a lot about galaxy evolution, and today’s paper reports what this diagram looks like at high redshifts.
