in terms of shock oscillation.

Recently, @nrs13 reported the possible association of QPOs in X-rays and jets in the form of radio flares in outbursting black hole sources through the accretion flow dynamics. Here also we find that the dynamics of the post-shock disc region plays a major role for the jet generation and the emitted radiation. In other words, post-shock disc seems to be the precursor of jets as well as QPOs according to our present study.

![ [*Top panel*]{}: Fourier spectra of shock location variation at the disc equatorial plane. Power spectra of bremsstrahlung flux variation calculated for SPH particles resides within the boundary of CENBOL ([*middle panel*]{}) and within the outflow region ([*bottom panel*]{}), respectively. Here, $\lambda_{\rm inj} = 1.63$ and $\alpha = 0.011$. In this case, we have consider simulated data of $\sim 20$ sec. Other parameters are same as Figure 1. Fundamental QPO frequency is obtained in both the cases $\sim 3.7$ Hz. However, significant differences in bremsstrahlung flux of CENBOL and outflow is observed. ](fig5a.eps "fig:"){width="45.00000%"} ![ [*Top panel*]{}: Fourier spectra of shock location variation at the disc equatorial plane.
