Galaxies with Shells in the Illustris Simulation: Metallicity Signatures

Galaxies with Shells in the Illustris Simulation: Metallicity Signatures

Stellar shells are low surface brightness arcs of overdense stellar regions, extending to large galactocentric distances. In a companion study, we identified 39 shell galaxies in a sample of 220 massive ellipticals ( M 200 crit > 6 × 10 12 M ⊙ ) from the Illustris cosmological...
