How Do Galaxies Form?
Sidney van den Bergh
It is currently believed that galaxies were assembled via chaotic hierarchical mergers between massive cold dark matter halos, in which baryonic star forming matter was embedded. O…
The Magnitude-Diameter Relation of Galaxies
Sidney van den Bergh
We investigate the dependence of the luminosity-diameter relation of galaxies on the environment. This study is based on a comparison between the 80 galaxies in the Shapley-Ames Ca…
Luminosity-Diameter Relations for Globular Clusters and Dwarf Spheroidal Galaxies
Sidney van den Bergh
It is shown that globular clusters and the dwarf spheroidal companions of the Galaxy have a different distribution of flattening values, and appear to occupy adjacent regions of th…
Globular Clusters and Dwarf Spheroidal Galaxies
Sidney van den Bergh
Traditionally globular clusters and dwarf spheroidal galaxies have been distinguished by using one or more of the following criteria: (1) mass, (2) luminosity, (3) size, (4) mass-t…
Some Musings on Galaxy Morphology
Sidney van den Bergh
Careful inspection of large-scale photographs of Shapley-Ames galaxies seems to show a smooth transition between the morphological characteristics of galaxies located on the narrow…
The Luminosity Distribution of Globular Clusters in Dwarf Galaxies
Sidney van den Bergh
The majority of the globular clusters associated with the Sagittarius dwarf galaxy are faint. In this respect it differs significantly from the globular cluster systems surrounding…
Structural Parameters of Mayall II = G1 in M31
J. Ma, R. de Grijs, D. Chen +6
Mayall II = G1 is one of the most luminous globular clusters (GCs) known in M31. New deep, high-resolution observations with the Advanced Camera for Surveys on the {\sl Hubble Spac…
A Comparison Between the Globular Clusters in NGC 5128 and the Galaxy
Sidney van den Bergh
Some of the properties of the globular clusters in NGC 5128 are compared to those of Galactic globular clusters. Assuming the color- metallicity relations that hold for Galactic gl…
The Dwarf Satellites of M31 and the Galaxy
Sidney van den Bergh
The satellite systems of M31 and the Galaxy are compared. It is noted that all five of the suspected stripped dSph cores of M31 companions are located within a projected distance o…
Globular Clusters in Dwarf and Giant Galaxies
Sidney van den Bergh
The luminosity distribution of globular clusters shows a dramatic dependence on parent galaxy luminosity. Dwarf galaxies contain far more faint globulars than do luminous galaxies.…
Diameters of Open Star Clusters
Sidney van den Bergh
The present paper presents a tabulation of data on all 600 Galactic open clusters for which it is presently possible to calculate linear diameters. As expected, the youngest `clust…
Globular Clusters in Dwarf Galaxies
Sidney van den Bergh
Data are presently available on the luminosities and half-light radii of 101 globular clusters associated with low-luminosity parent galaxies. The luminosity distribution of globul…
Spectral Types of Field and Cluster O-Stars
Sidney van den Bergh
The recent catalog of spectral types of Galactic O-type stars by Mai'z-Apella'niz et al. has been used to study the differences between the frequencies of various subtypes of O-typ…
Shapley-Ames Galaxies in the Blue and Infrared
Sidney van den Bergh
The Shapley-Ames Catalog of 1276 galaxies with B < 12.5 is compared with the Sanders et al. all sky sample of the 629 galaxies with 60 m flux density > 5.24 Jy. The fraction of Sha…
What are S0 (0) Galaxies?
Sidney van den Bergh
Among early-type galaxies with almost circular isophotes E0 and E1 galaxies are, at 99.3% significance, more luminous than face-on objects classified as S0 (0) and S(0) (1). This r…
Were the LMC Globular Clusters Formed in a Disk?
Sidney van den Bergh
The radial velocities of the 13 globular clusters in the Large Magellanic Cloud have a dispersion of 28 km s relative to the HI rotation curve of the LMC, compared to a disp…
The Formation and Evolution of Massive Star Clusters: Historical Overview
Sidney van den Bergh
Some factors connecting the evolutionary histories of galaxies with the characteristics of their cluster systems are reviewed. Unanswered questions include: How is one to understan…
History of the Local Group
Sidney van den Bergh
It is suggested that M31 was created by the early merger, and subsequent violent relaxation, of two or more massive metal-rich ancestral galaxies within the core of the Andromeda s…
Some Global Characteristics of the Galactic Globular Cluster System
Sidney van den Bergh
The relations between the luminosities , the metallicities , the Galactocentric radii , and the central concentration indices of Galactic globular clusters ar…
A Short History of the Missing Mass and Dark Energy Paradigms
Sidney van den Bergh
In 1900 it was believed that almost 100% of the mass of the Universe resided in stars. Now, in the year 2000, such stars (and cold gas) are known to account for only ~1% its mass.…
The Local Group of Galaxies
Sidney van den Bergh
Hubble's view that the Local Group (LG) is "a typical, small group of nebulae which is isolated in the general field" is confirmed by modern data. The total number of certain and p…
Comments on the Paper "Fundamental Stellar Photometry for Standards of Spectral Type on the Revised System of the Yerkes Spectral Atlas " by H.L. Johnson and W.W. Morgan (1953)
Sidney van den Bergh
This short paper is to be published as part of the centennial celebrations of the American Astronomical Society. It presents some historical background on, and discusses the import…
Formation of the Milky Way
J. E. Hesser, P. B. Stetson, W. E. Harris +9
We review observational evidence bearing on the formation of a prototypical large spiral galaxy, the Milky Way. New ground- and space-based studies of globular star clusters and dw…
A Large Proper-Motion Survey in Plaut's Low-Extinction Window
R. A. Mendez, R. M. Rich, W. F van Altena +3
We present preliminary results from the deepest and largest photographic proper-motion survey ever undertaken of the Galactic bulge. Our first-epoch plate material (from 1972-3) go…
