Lopsided Spiral Galaxies
by Chanda J. Jog, Francoise Combes
Publisher: arXiv 2008
Number of pages: 75
Description:
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.

First Light
by 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.

Dwarf-Galaxy Cosmology
by Regina Schulte-Ladbeck, at al. - 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.

Cosmic Rays in Galactic and Extragalactic Magnetic Fields
by F. Aharonian, A. Bykov, E. Parizot, V. Ptuskin, A. Watson - 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.
