Clusters of galaxies are the most recently assembled, massive, bound structures in the Universe. As predicted by General Relativity, given their masses, clusters strongly deform space-time in their vicinity. Clusters act as some of the most powerful gravitational lenses in the Universe. Light rays traversing through clusters from distant sources are hence deflected, and the resulting images of these distant objects therefore appear distorted and magnified.

The main purpose of this volume is to reproduce and make available for study, the larger and more interesting nebulae and clusters, sixty-eight in number. James Edward Keeler was the director of the Lick observatory 1898 - 1900.

This is a review of the properties of galaxy systems as determined from optical and infrared measurements. Covered topics are: clusters identification, global cluster properties and their scaling relations, cluster internal structure, etc.

The first dwarf galaxies, which constitute the building blocks of the collapsed objects we find today, had formed hundreds of millions of years after the big bang. This review describes the early growth of their small-amplitude seed fluctuations.

The cosmological gamma-ray burst phenomenon is reviewed. The broad observational facts and empirical relations of the GRB prompt emission and afterglow are outlined. A well-tested fireball shock model is introduced in a pedagogical manner.
