Protocluster Galaxies Love to Talk to Their Neighbors
Galaxy evolution is affected by a complex web of neighborhood politics between nearby galaxies. Today’s authors show that it’s the closest galaxies that matter the most in a galaxy protocluster!
Using eROSITA to look at Beautiful AGN Blow-outs
In today’s paper, the authors use eROSITA to assemble a sample of the beautiful blow-outs that can occur in galaxies when AGN turn on.
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!
Horse(head)s in the Galactic Ecosystem
All galaxies are a complex ecosystem of interactions between hydrogen gas and stars. In today’s paper, the authors look at the Horsehead Nebula to narrow down the details of those interactions.
Tracing Star Fuel in the Universe’s Smallest Galaxies
It’s really hard to see molecular hydrogen (the fuel that makes stars) directly, so astronomers have to use other spectral lines to guess how much is there. In today’s paper, the authors discuss how to do that in the smallest galaxies in the universe!
