Baby Photos of a Galaxy Cluster

While ClJ1446 is smaller and less massive than most present-day clusters, it is probably very similar to what they looked like 10 billion years ago. Therefore, this work can help improve our understanding of how our nearby galaxy clusters likely evolved.

The theory of a ‘galaxy main sequence’ has really taken hold of the astronomy community in the last few years. But how justified is this idea? Today’s paper: a challenge to the prevailing theory.

“Did I tell you about the time I was hit by a galaxy?”

“…and other lesson’s I learned when I was a spiral galaxy” — Our ideas of what happens to galaxies when they crash into each other comes mostly from simulations. But what if those results aren’t as trustworthy as we think? By watching a galaxy merger in the highest detail we can, we see that collisions may not be as destructive as we thought, and you just might survive a head-long crash into another galaxy.
