Low frequency m=1 normal mode oscillations of a self-gravitating disc
Kanak Saha
A continuous system such as a galactic disc is shown to be well approximated by an N-ring differentially rotating self-gravitating system. Lowest order (m=1) non-axisymmetric featu…

The thickness of HI in galactic discs under MOND: theory and application to the Galaxy
F. J. Sanchez-Salcedo, K. Saha, C. A. Narayan
The outskirts of galaxies are a very good laboratory for testing the nature of the gravitational field at low accelerations. By assuming that the neutral hydrogen gas is in hydrost…

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…
