We report on the first determination of the distance to the Coma Cluster based on surface brightness fluctuation (SBF) measurements obtained from Hubble Space Telescope WFPC2 observations of the bright E0 galaxy NGC 4881 in the Coma Cluster and ground-based observations of the standard E1 galaxy ...
The Coma-Leo I distance ratio coupled with estimates of the absolute distance to the Leo I group allows the Hubble constant to be determined, free of the uncertainties which arise when working with the Virgo cluster. Several high quality distance estimates are available from a variety of ...
We report on the first determination of the distance to the Coma Cluster from surface brightness fluctuation (SBF) measurements obtained from Hubble Space Telescope WFPC2 observations of the bright E0 galaxy NGC 4881 in the Coma Cluster and groundbased observations of the standard E1 galaxy NGC ...
This may be ascribed to the fact that only the random errors were taken into account in most of the previous studies with no allowance made for probable systematic errors. Figure 1 demonstrates the need for better error estimates in the art of distance estimation....
New observations using the Hubble Space Telescope yield a distance of 17.1 ± 1.8 Mpc to the Virgo cluster galaxy M100. This distance leads to a value of H 0 = 80 ± 17 km s−1 Mpc−1. A comparable value of H 0 is also derived from the Coma cluster using independent estimates ...
Optical SBF data from for the Virgo and Fornax clusters give the relative distances of these nearby fiducial clusters with 2% precision and constrain their internal structures. Observations in hand will allow us to tie the Coma cluster, the standard of comparison for distant cluster studies, into ...

None of the bursts that have been observed by BATSE are in\nnearby galaxies, nor is a signature from the Coma cluster or the ``Great Wall''\nlikely to be seen in the data at present.Jean Quashnock
The procedure of WSLMB and others in stepping a Virgo distance to the Coma Cluster and then using a Coma velocity that still contains a random component to determine H_0 is argued. The cosmic velocity for Virgo, calculated by reading a Hubble diagram of relative distances of 17 "remote" ...
