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.
A newly discovered quiescent galaxy in the early universe strains our understanding of galaxy evolution
2 new globular clusters detected by Gaia, and what we know about them.
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.
…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.
Do the Milky Way’s satellite galaxies have their own satellites?
