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.

Today’s paper looks at our own galaxy to measure its dark matter halo mass.
The satellites of galaxy Centaurus A seem to be in an unusual arrangement, which also has some fascinating cosmological implications!
We report on Day 2 of the virtual summer AAS meeting.
Is the Milky Way special? Or, as Dr. Marla Geha would like to know, are the satellite galaxies around the Milky Way special? Learn more at Dr. Geha’s #AAS238 plenary talk!
How does the structure of the smallest galaxies vary with different environments? Today’s authors use the ELVES survey to investigate!
