Probing the Structure of Accreting Compact Sources Through X-Ray Time Lags and Spectra
Xin-Min Hua, Demosthenes Kazanas, Wei Cui
We exhibit, by compiling all data sets we can acquire, that the Fourier frequency dependent hard X-ray lags, first observed in the analysis of aperiodic variability of the light cu…
Galactic Black Hole Binaries: High-Energy Radiation
J. E. Grove, J. E. Grindlay, B. A. Harmon +3
Observations of galactic BHCs made by the Compton GRO in the hard X-ray and gamma-ray bands have significantly enhanced our knowledge of the emission properties of these objects. U…
Frequency Dependent Lags - A Common Phenomenon of Accreting Sources
Xin-Min Hua, Demosthenes Kazanas, Wei Cui
The Fourier frequency dependent hard X-ray lag, first discovered from the analysis of aperiodic variability of the light curves of the black hole candidate Cygnus X-1, turns out to…
Modeling the Time Variability of Black Hole Candidates
Demosthenes Kazanas, Xin-Min Hua
We present model light curves, Power Spectral Densities (PSD) and time lags of accreting Black Hole Candidates (BHC) based on a recent model of these sources. According to our mode…
Cygnus X-1: X-ray Emission Mechanism and Geometry
Wei Cui, S. N. Zhang, J. H. Swank +3
We summarize recent observations of Cyg X-1 during its 1996 state transition. The results favor an emission geometry with a central optically thin corona surrounded by an optically…
Modeling the Hard X-Ray Lag and Energy Spectrum of Cyg X-1
Xin-Min Hua, Demosthenes Kazanas, Wei Cui
In an effort to model the observed energy spectrum of Cygnus X-1 as well as its hard X-ray lag by Comptonization in inhomogeneous clouds of hot electrons with spherical geometry an…
