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 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.

On the Origin (and Evolution) of Baryonic Galaxy Halosby Duncan A. Forbes, Ericson D. Lopez - MDPI AG
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.

First Lightby Abraham Loeb - 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.
