Using simulations to explore the fate of galaxies falling into clusters
Could feedback from active galactic nuclei play an important role in the smallest of galaxies?
How do galaxies transform from blue, star-forming discs into the massive red-and-dead ellipticals that we observe so frequently? Post-starburst galaxies, caught in this transition phase, might hold the answers to this puzzle in galaxy evolution.
