X-Ray Spectra of The High-Mass X-RAY Binary 4U~1700-37 using BeppoSAX, Suzaku and RXTE Observations
Elena Seifina, Lev Titarchuk, Nikolai Shaposhnikov
We present an X-ray spectral analysis of the high-mass binary 4U~1700-37 during its hard-soft state evolution. We use the BeppoSAX, Suzaku and RXTE (Rossi X-ray Timing Explorer), S…
BEPPOSAX and RXTE spectral study of the low-mass X-ray binary 4u~1705-44. Spectral hardening during the banana branch
Elena Seifina, Lev Titarchuk, Chris Shrader +1
We analyze the X-ray spectra of the atoll 4U~1705-44 when the source undergoes the island-banana state transition. We use the Rossi X-ray Timing Explorer (RXTE) and BeppoSAX observ…
Black hole mass determination in the X-ray binary 4U 1630--47: Scaling of spectral and variability characteristics
Elena Seifina, Lev Titarchuk, Nikolai Shaposhnikov
We present the results of a comprehensive investigation on the evolution of spectral and timing properties of the Galactic black hole candidate 4U 1630--47 during its spectral tran…
Spectral evolution of the X-ray nova XTE J1859+226 during its outburst observed by BeppoSAX and RXTE
R. Farinelli, L. Amati, N. Shaposhnikov +7
We report results of an extensive analysis of the X-ray nova XTE J1859+226 observed with BeppoSAX and RXTE during its 1999 outburst. We modelled the source spectrum with a multicol…
Advances in the RXTE Proportional Counter Array Calibration: Nearing the Statistical Limit
Nikolai Shaposhnikov, Keith Jahoda, Craig Markwardt +2
During its 16 years of service the Rossi X-ray Timing Explorer (RXTE) mission has provided an extensive archive of data, which will serve as a primary source of high cadence observ…
On the nature of QPO phase lags in black hole candidates
Nikolai Shaposhnikov
Observations of quasi-periodic oscillations (QPOs) in X-ray binaries hold a key to understanding many aspects of these enigmatic systems. Complex appearance of the Fourier phase la…
