On the origin of accretion flow photon index-quasi-periodic oscillation frequency (Γ-vQPO) relation.

ABSTRACT: MAXI J1535-571 outburst was dramatic and the accretion flow exhibits spectra-temporal characteristics related to one another. In this study, MAXI J1535-571 data observed by SWIFT/BAT (Swift/Burst Alert Telescope) and MAXI/GSC (Monitor of All-sky X-ray Image/Gas slit camera) was analyzed. The physical and phenomenological models that explain the components of the accretion flow were adopted in fitting/modelling the data in XSPEC v12.10.1f. The accretion flow characteristics and photon index-quasi-periodic oscillation frequency (Γ-vQPO) relation and their correlations were determined. The resonance condition in the range of (0.507-1.248) ± 0.080 indicates that the components of the accretion flow timescales are comparable. The QPO frequency of 0.840-4.961 Hz was obtained. This affirms the TC
