Cluster Lenses
by Jean-Paul Kneib, Priyamvada Natarajan
Publisher: arXiv 2012
Number of pages: 120
Description:
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.

Lopsided Spiral Galaxies
by Chanda J. Jog, Francoise Combes - 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.

Observations of the High Redshift Universe
by Richard S. Ellis - 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.

Large Scale Structure of the Universe
by Alison L. Coil - 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.

Gamma-Ray Bursts: Progress, Problems and Prospects
by Bing Zhang, Peter Meszaros - 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.
