Using a generalized non-spherical, multi-transonic accretion flow model, we analytically calculate the normalized QPO frequency ${\bar {\bf {\nu}}}_{qpo}$ of galactic black hole candidates in terms of dynamical flow variables and self-consistently study the dependence of ${\bar {\bf {\nu}}}_{qpo}$ on such variables. Our results are in fairly close agreement with the observed QPO frequencies of GRS 1915+105. We find that ${\bar {\bf {\nu}}}_{qpo}$ is quite sensitive to various parameters… Expand
Quasi-periodic oscillation frequencies and mass-outflow rates in black hole powered Galactic microquasars

Multi-transonic spherical-type flows around massive black holes: galactic potential induced standing isothermal shocks
Accretion on length-scales of interstellar or even intergalactic is particularly relevant, in the context of spherical or quasi-spherical hot mode accretion, supposedly powering low excitation radioExpand
Hysteresis effects and diagnostics of the shock formation in low angular momentum axisymmetric accretion in the Kerr metric
Abstract The secular evolution of the purely general relativistic low angular momentum accretion flow around a spinning black hole is shown to exhibit hysteresis effects. This confirms that aExpand
Shock oscillation model for quasi-periodic oscillations in stellar mass and supermassive black holes
We numerically examine centrifugally supported shock waves in 2D rotating accretion flows around a stellar mass (10 M⊙) and a supermassive (10 6 M⊙) black holes over a wide range of input accretionExpand
Radiative Shocks in Rotating Accretion Flows around Black Holes
It is well known that the rotating inviscid accretion flows with adequate injection parameters around black holes could form shock waves close to the black holes, after the flow passes through theExpand
