[87.11] How bright are the BO galaxies?
Esther L. Zirbel (STScI)
We construct the luminosity function of red (with rest frame (B-V)o>0.75)
and blue (0.750.10) galaxies in rich groups (with 15 members more)
at low (z~0.2) and high (z~0.4) redshifts, and we show that the main
difference between these groups is the extra population of bright blue
galaxies at higher redshifts which have rest frame V magnitudes ranging
from -22.5 to -21.5. We speculate that these may be the so-called
