Galaxies and Clusters of Galaxies

2002
The leap into deep space outside our Milky Way Galaxy, into the realm of the distant galaxies (or the extragalactic nebulae, as they were formerly called), and the beginnings of a cosmology based on observations, will be considered throughout history to be one of the most important achievements of the 20th century.

Clustering due to cluster galaxies

Monthly Notices of the Royal Astronomical Society, 1991
A calculation of the contribution that galaxies in clusters make towards the clustering exhibited by all galaxies is presented. It is shown that, within observational uncertainties, cluster galaxies may be responsible for all the clustering measured by the galaxy-galaxy correlation function (GGCF). This confirms that cluster galaxies make a significant

Globular Clusters and Galaxy Formation in Clusters of Galaxies

1984
Taken at face value globular cluster counts indicate that: (1) Most elliptical galaxies in rich clusters were not formed by merging spirals and (2) central galaxies in rich clusters were already very special at the time when they were forming globular clusters.
