Correlations between X-ray Spectral and Timing Characteristics in Cyg X-2
Lev Titarchuk, Sergey Kuznetsov, Nikolai Shaposhnikov
Correlations between the quasi-periodic oscillations (QPOs) and the spectral power-law index have been reported for a number of black hole candidate sources and for four neutron st…

Determination of Black Hole Mass in Cyg X-1 by Scaling of Spectral Index-QPO Frequency Correlation
Nickolai Shaposhnikov, Lev Titarchuk
It is well established that timing and spectral properties of Galactic Black Hole (BH) X-ray binaries (XRB) are strongly correlated. In particular, it has been shown that low frequ…
