large bulges

• by williamaskew

  I have noticed nearly all of the red galaxies i have observed today have bulges larger than the blues we usually see. Does this imply bulges get larger mass density as it is quenching or does a large dense bulge contribute to the quenching mechanism of a galaxy?

  Perhaps neither. Don't forget that only half the galaxies we get to classify are 'post-quenched', the other half are controls, matched for stellar mass and redshift!

  Yes it did seem some of these didn't belong but the Lange bulge does seem to be a constant in the red galaxies here.
