Large Scale Structure of the Universe
by Alison L. Coil
Publisher: arXiv 2012
Number of pages: 43
Description:
Galaxies are not uniformly distributed in space. 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, known as voids, contain very few galaxies and span the volume in between these structures.

Lopsided Spiral Galaxiesby 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.

Cluster Lensesby Jean-Paul Kneib, Priyamvada Natarajan - 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.
