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.

Basics of inflationary models for the early universe, concentrating on the generation of density fluctuations from scalar-field dynamics. The subsequent gravitational dynamics of these fluctuations in dark matter in a Friedmann model are described.

The old dream of integrating into one the study of micro and macrocosmos is now a reality. Cosmology, astrophysics, and particle physics intersect in a scenario of cosmic structure formation and evolution called Lambda Cold Dark Matter model.

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.
