Dynamical Imprint of Dark Matter Halo and Interstellar Gas on Spiral Structure in Disk Galaxies
Soumavo Ghosh
This thesis investigates the dynamical effect of two structural components of disk galaxies, namely, the dark matter halo and the interstellar gas on the origin and persistence iss…

Effect of finite disk-thickness on swing amplification of non-axisymmetric perturbations in a sheared galactic disk
Soumavo Ghosh, Chanda J. Jog
A typical galactic disk is observed to have a finite thickness. Here, we present the study of the physical effect of introduction of finite thickness on the generation of small-sca…

Dwarf irregular galaxies with extended HI gas disks: Suppression of small-scale spiral structure by dark matter halo
Soumavo Ghosh, Chanda J. Jog
Dwarf irregular galaxies with extended HI disk distributions, such as DDO 154, allow measurement of rotation curves, hence deduction of dark matter halo properties to large radial…
