Book cover: Gamma-Ray BurstsGamma-Ray Bursts
- Wikipedia ,
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.

Book cover: Cosmological Evolution of GalaxiesCosmological Evolution of Galaxies
by - arXiv ,
I review the subject of the cosmological evolution of galaxies, including different aspects of growth in disk galaxies, by focussing on the angular momentum problem, mergers, and their by-products. I discuss the alternative to merger-driven growth.

Book cover: Large Scale Structure of the UniverseLarge Scale Structure of the Universe
by - arXiv ,
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.

Book cover: Cluster LensesCluster Lenses
by - arXiv ,
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.

Book cover: Photographs of Nebulae and ClustersPhotographs of Nebulae and Clusters
by - University of California Publications ,
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.

Book cover: Cosmic Rays in Galactic and Extragalactic Magnetic FieldsCosmic Rays in Galactic and Extragalactic Magnetic Fields
by - arXiv ,
We review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the observations.

Book cover: Gamma-Ray Bursts: Progress, Problems and ProspectsGamma-Ray Bursts: Progress, Problems and Prospects
by - arXiv ,
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.

Book cover: First LightFirst Light
by - arXiv ,
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.

Book cover: Dwarf-Galaxy CosmologyDwarf-Galaxy Cosmology
by - Hindawi Publishing ,
Dwarf galaxies provide opportunities for drawing inferences about the processes in the early universe by observing our Local Group and its vicinity. This issue is a snapshot of the current state of the art of dwarf-galaxy cosmology.

Book cover: Understanding Galaxy Formation and EvolutionUnderstanding Galaxy Formation and Evolution
by - arXiv ,
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.

Book cover: Observations of the High Redshift UniverseObservations of the High Redshift Universe
by - arXiv ,
In these lectures aimed for non-specialists, the author reviews progress in understanding how galaxies form and evolve. The first results presented here provide important guidance on how we will use more powerful future facilities.

Book cover: Inflationary Cosmology and Structure FormationInflationary Cosmology and Structure Formation
by - arXiv ,
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.

Book cover: Galaxy systems in the optical and infraredGalaxy systems in the optical and infrared
by - arXiv ,
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.

Book cover: Atlas of Peculiar GalaxiesAtlas of Peculiar Galaxies
by - California Institute of Technology ,
The Atlas of Peculiar Galaxies is a catalog of peculiar galaxies produced by Halton Arp. A total of 338 galaxies are presented in the atlas, which was originally published in 1966 by the California Institute of Technology.

Book cover: Lopsided Spiral GalaxiesLopsided Spiral Galaxies
by - arXiv ,
The light distribution in the disks of many galaxies is non-axisymmetric or 'lopsided' with a spatial extent larger along one half of a galaxy than the other. In this review, the observations to measure the lopsided distribution will be discussed.
