Spinning up massive classical bulges in spiral galaxies
Spiral galaxies are formed with a central bulge, around which their spiral arms are wrapped. But how do galaxy bulges form?
“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.
When A Bar Hits an Arm
…you can get stars, and a dumbbell of light. We’ll take a closer look at one of them.
Exploring the law of star-formation through a spatially resolved study of two spiral galaxies
Today’s guest post from Nimisha Kumari looks at how different properties of galaxies can affect the Schmidt-Kennicutt Law.
Dust and the Occult
Pairs of occulting galaxies allow for the dust in galaxies to be mapped very accurately and give insight into the attenuation law in the outskirts of galaxies.
SETI Near and Far – Searching for Alien Technology
Finding extraterrestrial intelligence would be one of the most enlightening and profound discoveries in history. Today’s post looks at two potential means of finding extraterrestrials by seeing their advanced technology elsewhere in the Milky Way and the Universe.
