No QPO time lags from Sco X-1 as seen with EXOSAT: a comparison with Cyg X-2
Stefan W. Dieters, Brian A. Vaughan, Erik Kuulkers +2
We have measured the phase-delay and rms amplitude spectra of CygX-2 and ScoX-1. Using EXOSAT data from the normal branch of CygX-2 we confirm earlier (Ginga) results, showing that…
Kilohertz Quasi-Periodic Oscillation Peak Separation is not Constant in the Atoll Source 4U 1608-52
Mariano Mendez, Michiel van der Klis, Rudy Wijnands +3
We present new Rossi X-ray Timing Explorer observations of the low-mass X-ray binary 4U 1608-52 during the decay of its 1998 outburst. We detect by a direct FFT method the existenc…
Quasi-Periodic Oscillations in Black Hole Candidates as an Indicator of Transition Between Low and High States
Robert E. Rutledge, Walter H. G. Lewin, Michiel van der Klis +6
By comparing positions on a spectral color-color diagram from 10 black hole candidates (BHCs) observed with Ginga (1354-64, 1826-24, 1630-47, LMC X-1, LMC X-3, GS 2000+25, GS 2023+…
Discovery of a 57-69 Hz quasi-periodic oscillation in GX13+1
Jeroen Homan, Michiel van der Klis, Rudy Wijnands +2
We report the discovery of a quasi-periodic oscillation (QPO) at 61.0+/-1.7 Hz with the Rossi X-Ray Timing Explorer in the low-mass X-ray binary and persistently bright atoll sourc…
Discovery of KiloHertz Quasi-Periodic Oscillations in 4U 1735-44
Rudy Wijnands, Michiel van der Klis, Mariano Mendez +5
We discovered a single kHz quasi-periodic oscillation (QPO) near 1150 Hz in the Rossi X-ray Timing Explorer X-ray light curve of the low mass X-ray binary and atoll source 4U 1735-…
The Physical Interpretation of X-ray Phase Lags and Coherence: RXTE Observations of Cygnus X--1 as a Case Study
M. A. Nowak, J. B. Dove, B. A. Vaughan +1
There have been a number of recent spectral models that have been successful in reproducing the observed X-ray spectra of galactic black hole candidates (GBHC). However, there stil…
