Finding the Missing Bridges Between Galaxy Clusters
In today’s paper, the authors look for the more than 50% of matter in the universe that’s ‘missing’ from our count by searching for bridges between clusters of galaxies.
A Galaxy Lost in the Gamma-Ray Sauce
We’re still trying to understand what caused the emission seen in the Fermi Bubbles, massive lobes of gamma rays extending out of the Milky Way. Today’s authors argue that one of the Milky Way’s satellite galaxies is probably not an ingredient!
Shining (the wrong?) light on Self-Interacting Dark Matter
Dark matter is very hard to study because, well, it’s dark. Today’s authors explore how the light we can see in galaxy clusters might not trace dark matter as well as we thought.
Blowing Away Star Formation with Warm Molecular Gas
In today’s paper, the authors use JWST to investigate how warm, star-forming molecular gas is blown away by AGN.
Teamwork Makes the Intensity-Mapping Dream Work
Line intensity mapping is an exciting new technique used to map the universe, but it struggles with astrophysical foregrounds. Today’s authors use the power of team work (data at other wavelengths) to make an intensity-mapping detection.
