Lopsided Spiral Galaxies

Lopsided Spiral Galaxies
by Chanda J. Jog, Francoise Combes

Publisher: arXiv 2008
Number of pages: 75

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.
