AbstractWe investigate the use of brightest cluster galaxies (BCGs) as standard candles for measuring galaxy peculiar velocities on large scales. We have obtained precise large-format CCD surface photometry and redshifts for an all-sky, volume-limited (z <= 0.05) sample of 119 BCG. We reinvestigate the Hoessel (1980) relationship between the metric luminosity, L_m_, within the central 10 h^-1^ kpc of the BCGs and the logarit ...
