Misalignment between cold gas and stellar components in early-type galaxies
Misalignment between cold gas and stellar components in early-type galaxies
Recent work suggests blue ellipticals form in mergers and migrate quickly from the blue cloud of star-forming galaxies to the red sequence of passively evolving galaxies, perhaps as a result of black hole feedback. Such rapid reddening of stellar populations implies that large gas reservoirs in the pre-merger star-forming pair …
