Transonic behaviour and stability analysis of quasi-viscous black hole accretion
Deepika B. Ananda, Soumini Chaudhury, Tapas K. Das +2
Analytical studies of black hole accretion usually presumes the stability of the stationary transonic configuration. Various authors in the past several decades demonstrated the va…
Rotation Curve of the Milky Way out to 200 kpc
Pijushpani Bhattacharjee, Soumini Chaudhury, Susmita Kundu
The rotation curve (RC) of our Galaxy, the Milky Way, is constructed starting from its very inner regions (few hundred pc) out to a large Galactocentric distance of kpc…
Deriving the velocity distribution of Galactic Dark Matter particles from rotation curve data
Pijushpani Bhattacharjee, Soumini Chaudhury, Susmita Kundu +1
The velocity distribution function (VDF) of the hypothetical Weakly Interacting Massive Particles (WIMPs), currently the most favored candidate for the Dark Matter (DM) in the Gala…
Direct detection of WIMPs : Implications of a self-consistent truncated isothermal model of the Milky Way's dark matter halo
Soumini Chaudhury, Pijushpani Bhattacharjee, Ramanath Cowsik
Direct detection of Weakly Interacting Massive Particle (WIMP) candidates of Dark Matter (DM) is studied within the context of a self-consistent truncated isothermal model of the f…
Critical properties and stability of stationary solutions in multi-transonic pseudo-Schwarzschild accretion
Soumini Chaudhury, Arnab K. Ray, Tapas Kumar Das
For inviscid, rotational accretion flows, both isothermal and polytropic, a simple dynamical systems analysis of the critical points has given a very accurate mathematical scheme t…
