[87.11] How bright are the BO galaxies?

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 BO-galaxies.
