Two Paths Diverged in a Cosmological Simulation: on the Formation Pathways of S0 Galaxies
Today’s bite explores the two main pathways of S0 galaxy formation, ram-pressure stripping and galaxy mergers.
The Magnetic Menagerie of NGC 1097
In the heart of the barred spiral galaxy NGC 1097, there’s more to the magnetic field than meets the eye.
Red, dead (and flat?) galaxies in distant clusters
Most galaxies are either star-forming disks, or red, dead spheroids. But, have galaxy clusters now shown that this divide isn’t quite so clear?
Galactic thick discs bursting onto the scene
The Milky Way’s disc is made up of two components — but where did they come from?
Galactic Fidget Spinner: Unraveling the Milky Way’s Spiral Structure
Ever wondered how astronomers study the structure of our own Galaxy from within? Read on to find out how the Gaia mission helps us in this regard!
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.
