The Luminosity-Line-Width Relations and the Value of Ho,ground contamination in the Virgo Cluster is presented. It is shown that this contamination is responsible for much of the controversy regarding the distance to the Virgo Cluster. The absolute calibration is examined and it appears that the technique is now limited by the uncertainty in the . distan充气球 发表于 2025-3-26 08:18:16
Observational Status of Ho,d the cosmic recession velocity of the cluster (v = 1144 ±18 km s.) within a nearly Machian frame can be determined using . distances to more distant clusters. The resulting value of the Hubble constant — freed from all velocity perturbations — is H. = 52 km s.Mpc.. The formal error of this determinglamor 发表于 2025-3-26 12:01:07
