Try this interactive page that allows you to identify galaxies with stellar shells in the Illustris simulation.
Identify shell galaxies
Shells in a nutshell
You might have seen the beautiful shell galaxy below in the Astronomy Picture of the Day and wondered how these shells are formed. I summarize our results in just 14 tweets (or press on the text in the tweet below). If you want to learn more, check our paper here. And try identifying a few shell galaxies at the bottom of the page before you leave!
How do shells form? Through beautiful galaxy mergers! keep on reading for more details & pics! Shell galaxies are relatively common, ~18% of massive galaxies (>6 x 10^12 solar masses) have shells. We used the Illustris cosmological simulation to study them pic.twitter.com/tkJ9PtgDuu
