Bending instabilities of m=1 mode in disc galaxies: interplay between dark matter halo and vertical pressure
Sagar S. Goyary, Kanak Saha, H. Shanjit Singh +1
A self-gravitating, differentially rotating galactic disc under vertical hydrostatic equilibrium is supported by the vertical pressure gradient force against the gravitational coll…
Gravitational potential energy of a multi-component galactic disk
Suchira Sarkar, Chanda J. Jog
We calculate ab initio the gravitational potential energy per unit area for a gravitationally coupled multi-component galactic disk of stars and gas, which is given as the integrat…
Vertical stellar density distribution in a non-isothermal galactic disc
Suchira Sarkar, Chanda J. Jog
The vertical density distribution of stars in a galactic disc is traditionally obtained by assuming an isothermal vertical velocity dispersion of stars. Recent observations from SD…
General model of vertical distribution of stars in the Milky Way using complete Jeans equations
Suchira Sarkar, Chanda J. Jog
The self-consistent vertical density distribution in a thin, isothermal disc is typically given by a sech^2 law, as shown in the classic work by Spitzer (1942). This is obtained as…
Flaring stellar disk in the low surface brightness galaxy UGC 7321
Suchira Sarkar, Chanda J. Jog
We theoretically study the vertical structure of the edge-on low surface brightness (LSB) galaxy UGC 7321. This is one of the few well-observed LSBs. We modeled it as a gravitation…
The constraining effect of gas and the dark matter halo on the vertical stellar distribution of the Milky Way
Suchira Sarkar, Chanda J Jog
We study the vertical stellar distribution of the Milky Way thin disk in detail with particular focus on the outer disk. We treat the galactic disk as a gravitationally coupled, th…
