A serving of X-rays in a stack of galaxies
Quiescent galaxy pancakes are filled with berry jam across cosmic time, and other lessons from galaxy stacking
Some Constructive Feedback on Feedback Models
For the first time, astronomers have detected the hot, diffuse circumgalactic medium — a perfect testbed for models of galactic feedback. So, how do our current models stack up against the new data?
Judging a Galaxy by its Cover
We’re always told not to judge a book by it’s cover, but what about galaxies? Today’s authors try to find out!
When good galaxies go bad: a new mechanism for galaxy death
Why are so many modern galaxies not actively forming stars? Today’s guest post by Katherine Lee explores one mechanism that may quench star formation in Milky Way-like galaxies.
Forecasting the obscured first few billion years
What will JWST reveal about the obscured early Universe? Today’s authors process simulations to find out
A spiral galaxy that doesn’t play by the rules
Galaxies in the middle of clusters are usually huge, elliptical galaxies. So what is this spiral-shaped imposter doing here?
