Tracing the power-law component in the energy spectrum of black hole candidates as a function of the QPO frequency
F. Vignarca, S. Migliari, T. Belloni +2
We investigated the relation between the centroid frequency of the quasi-periodic oscillation observed in the power density spectra of a sample of galactic black-hole candidates wi…
The mass of the neutron star in the low-mass X-ray binary 2A 1822-371
Peter G. Jonker, Michiel van der Klis, Paul J. Groot
Using phase resolved spectroscopic observations obtained with the Ultraviolet and Visual Echelle Spectrograph on ESO's Kueyen Very Large Telescope supplemented by spectroscopic obs…
The 2002 outburst of the microquasar XTE J1550-564
A. P. Colombo, T. Belloni, J. Homan +2
We present results of spectral and timing analysis based on 11 RXTE PCA/HEXTE observations of the microquasar XTE J1550-564 during its last outburst in January 2002. The observed b…
GX 339-4: back to life
T. Belloni, E. Nespoli, J. Homan +4
We report preliminary results of a RossiXTE campaign on the 2002 outburst of the black-hole candidate GX 339-4. We show power density spectra of five observations during the early…
The atoll source 4U 1608-52 is not a Z source
S. van Straaten, M. van der Klis, M. Mendez
We have studied the spectral and timing behaviour of the atoll source 4U 1608-52. We find that the timing behaviour of 4U 1608-52 is almost identical to that of the atoll sources 4…
Do High Frequency QPOs Depend on Phase of Low Frequency QPOs in XTE J1550-564 ?
W. Yu, M. van der Klis, R. Fender
We have studied the dependence of the high frequency Quasi-periodic Oscillation (QPO) (~284 Hz) on the phase of the low frequency QPO (~6 Hz) in the black hole X-ray binary XTE J15…
