Make Our Galaxy Grow: Massive Disk Galaxies in the Local Universe
Major galaxy mergers are thought to be one of the main ways of producing massive elliptical galaxies. Surprisingly though, some of the most massive galaxies in the local universe have gas disks. Here’s how they might be made.
Good Luck Sorting This Hat
Sorting the Sombrero galaxy into a galaxy classification is difficult to do, but new evidence suggests that like Harry Potter, the Sombrero galaxy may fit into more than one category.
Making a Splash
Today’s paper takes a closer look at the after-effects of the Milky Way’s last major collision with another galaxy.
Inconstant, Fine Structures
Using simulations of a Milky Way-sized elliptical galaxy, astronomers study how stellar substructures can tell us about past merger events.
