Distribution of Supernovae in Spiral Galaxies
Sidney van den Bergh
Data are presently available on 156 supernovae (SNe) of known type that have occurred in spirals of types Sa-Sc having inclinations i < 70 degrees. The surface density distribution…
Some Integrated Properties of Galactic Globular Clusters
Sidney van den Bergh
The luminosities of globular clusters are found to correlate with their half-light radii. The most luminous clusters have half-light radii r ~ 3 pc. Mean cluster luminosities are <…
Formation of the Galaxy
Sidney van den Bergh
Current ideas on the formation of the Galaxy are reviewed. Many of the observed characteristics of our Milky Way System are consistent with a scenario in which the Galaxy formed in…
Mergers of Globular Clusters
Sidney van den Bergh
Globular clusters with composite color-magnitude diagrams, such as NGC 1851, NGC 2808 and Fornax No. 3, might have formed by mergers. It is suggested that each of these objects had…
A Morphological Catalog of Galaxies in the Hubble Deep Field
Sidney van den Bergh, Roberto Abraham, Richard Ellis Nial Tanvir +2
We present a catalog of morphological and color data for galaxies with mag in the {\em Hubble Deep Field} (Williams et al. 1996). Galaxies have been inspected and (when po…
The Extragalactic Distance Scale
Sidney van den Bergh
Cepheid variables are used to derive a Virgo cluster distance of 16.0 +/- 1.5 Mpc. In conjunction with the Coma velocity and the well-established Coma/Virgo distance ratio, this yi…
