Gamma-Ray Bursts: Progress, Problems and Prospects
by Bing Zhang, Peter Meszaros
Publisher: arXiv 2008
Number of pages: 87
The cosmological gamma-ray burst (GRB) phenomenon is reviewed. The broad observational facts and empirical phenomenological relations of the GRB prompt emission and afterglow are outlined. A well-tested, successful fireball shock model is introduced in a pedagogical manner. Several important uncertainties in the current understanding of the phenomenon are reviewed.

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.

Galaxy halos provide important clues to the origin and evolution of galaxies. This volume brings together the latest simulations and deep observations of galaxy halos, focusing on the baryonic (star and gas) component of halos.
Gamma-ray bursts are flashes of gamma rays associated with extremely energetic explosions in distant galaxies. They are the brightest electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several minutes.

Clusters of galaxies are the most recently assembled, massive, bound structures in the Universe. Given their masses, clusters strongly deform space-time in their vicinity. Clusters act as the most powerful gravitational lenses in the Universe.
