Sloshing in the Universe’s Biggest Bathtub
The centers of galaxy clusters are energetic and exciting places. Today’s paper explores why Abell 2495 is particularly exciting – it’s sloshing around!

Brand new data could force us to re-think how galaxies form and evolve in the early Universe — but there’s no need to panic!
The distribution of galaxies clusters (BAOs) are a beloved tool for cosmological analysis. But what about cosmic voids? Stare into the void, and you might just learn something new!
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?
Today’s authors explore a nearby analog of some of the earliest galaxies to form in the universe and measure a metallicity gradient.
How does a galaxy’s past impact its present day surroundings? Today’s authors use genetically modified simulations to investigate the effect of merger histories on stellar haloes.
