How Galaxy Mergers Can Bridge The Stellar Age Gap in Spiral Arms
Can galaxy interactions help young and old stars in spiral arms get to know each other? These authors’ simulations may have an answer!

This galaxy simulation can fit so many stars and gas particles in it
Simulating an entire galaxy is not easy if you want your result sometime this century. But today’s paper brings us a neat trick that might just help speed things up.

[Beyond] Intro to Astrophysical Simulation Jargon
This Beyond post will go through the basics of numeric simulation jargon with diagrams and examples to help you get moving in astrophysical simulations.
Strength in Numbers: How Cloud Communities Weather Galactic Storms
Classic theory says only big clouds should survive galactic winds, but these new simulations show that’s not the whole story. Whether a cloud lives or dies depends not only on its size, but also on the environment it’s sitting in.
