Pattern Speed of Lopsidedness in Galactic Disks
Chanda J. Jog
The disks of spiral galaxies commonly show a lopsided mass distribution, with a typical fractional amplitude of 10 % for the Fourier component m=1. This is seen in both stars and g…
Lopsided Spiral Galaxies
Chanda J. Jog, Francoise Combes
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, as in M101. Rece…
The Flattened Dark Matter Halo of M31 as Deduced from the Observed HI Scale Heights
Arunima Banerjee, Chanda J. Jog
In this paper, we use the outer-galactic HI scale height data as well as the observed rotation curve as constraints to determine the halo density distribution of the Andromeda gala…
Multiple minor mergers: formation of elliptical galaxies and constraints for the growth of spiral disks
Frederic Bournaud, Chanda J. Jog, Francoise Combes
Multiple, sequential mergers are unavoidable in the hierarchical build-up picture of galaxies, in particular for the minor mergers that are frequent and highly likely to have occur…
Lopsidedness and Sloshing in Centres of Advanced Mergers of Galaxies
Chanda J. Jog, Aparna Maybhate
We measure the non-axisymmetry in the luminosity distribution in the central few kpc of a sample of advanced mergers of galaxies, by analyzing their 2MASS images. All mergers show…
Global lopsided instability in a purely stellar galactic disc
K. Saha, F. Combes, C. Jog
It is shown that pure exponential discs in spiral galaxies are capable of supporting slowly varying discrete global lopsided modes, which can explain the observed features of lopsi…
