Inference on disk-jet connection of MAXI J1836–194 from spectral analysis with the TCAF solution

Galactic transient black hole candidate(BHC) MAXI J1836–194 was discovered on 2011 Aug30, by MAXI/GSC and Swift/BAT. The source activity during this outburst continued for ~ 3 months before entering into the quiescent state. It again became active in March 2012 and continued for another~ 2 months. In this paper, 3-25 keV RXTE/PCA spectra from the 2011 outburst and 0.5-10.0 keV Swift/XRT data during its 2012 outburst are analyzed with the two-component advective flow(TCAF)model based fits files in XSPEC. We calculate the X-ray contributions coming from jets/outflow using a newly developed method based on the deviation of the TCAF model normalization. We also study the correlation between observed radio and estimated jet X-ray fluxes. The correlation indices(b) are found to be 1.79 and 0.61, when the 7.45 GHz Very Large Array(VLA) radio flux is correlated with the total X-ray and jet X-ray fluxes in 3-25 keV range respectively. It has been found that the jet contributes in X-rays up to a maximum of 86% during its 2011 outburst. This makes the BHC MAXI J1836–194 strongly jet dominated during the initial rising phase.
