Lopsided Spiral Galaxies

The light distribution in the disks of many galaxies is non-axisymmetric or 'lopsided' with a spatial extent much larger along one half of a galaxy than the other. The disk lopsidedness can be used as a diagnostic to study the halo asymmetry. This is an emerging area in galactic structure and dynamics. In this review, the observations to measure the lopsided distribution, as well as the theoretical progress made so far to understand its origin and properties, and the related open problems will be discussed.

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.

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.

On large scales the Universe displays coherent structure, with galaxies residing in groups and clusters, which lie at the intersections of long filaments of galaxies. Vast regions of relatively empty space span the volume between these structures.

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.
