Simulation of Compact Groups of Galaxies
Astrophysics and Space Science, 1986Self-consistent simulations of seven groups of galaxies with halos have been performed to find a constraint upon the size of missing halos around spiral galaxies. An initial galaxy, which consists of 100 superstars, has half-mass radius 41 kpc and central velocity dispersion 235 km s−1. The simulations start from the epoch of maximum expansion.

Populations In Local Group Galaxies
Annual Review of Astronomy and Astrophysics, 1989developed primarily by W. Baade in the 1950s, was inspired by the apparent dichotomy of galaxy content. Some galaxies (spirals and irregulars) seemed to be made up largely of bright, blue stars, with an admixture of interstellar material, whereas others (ellipticals) seemed to be made up exclusively offaint red stars (13). Baade called the two kinds of
