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.

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.
