- W1993018933 abstract "We measure the distribution of velocity dispersions of groups of galaxies identified in the Updated Zwicky Catalog, and we use the distribution to derive the group mass function. We introduce a new method that makes efficient use of the entire magnitude-limited catalog. Our determination of n(≥σT) includes a significant contribution from low-luminosity systems that would be missing in a volume-limited sample. We start from a model for the probability density function of the total number of group members and reproduce the observed distribution. We take several effects, such as the local fluctuations in volume density, limited sampling, and group selection, into account. We estimate the relation between total number of members, total luminosity, and true velocity dispersion. We can then reproduce not only the observed distribution of σv, but also the distributions of the number of group members, the total group luminosity, and virial mass. The best fit to the data in the true velocity dispersion range 100 km s-1 ≤ σT ≤ 750 km s-1 is a power-law model with a slope d log n(≥σT)/d log σT = -3.4 (-2.1, -5) and a normalization n(σT ≥ 750 km s-1) = (1.27 ± 0.21) × 10-5 h3 Mpc-3, where σT is the true velocity dispersion of a group. The predictions of cold dark matter models are consistent with the mass function we derive from this distribution of velocity dispersions." @default.
