Abstract:
We present the results of the analysis of a large data base of X-ray
observations of 22 galactic black hole transients with the Rossi X-Ray
Timing Explorer throughout its operative life for a total exposure
time of ∼12ms. We excluded persistent systems and the peculiar
source GRS 1915+105, as well as the most recently discovered sources.
The semi-automatic homogeneous analysis was aimed at the detection of
high-frequency (100-1000Hz) quasi-periodic oscillations (QPO), of
which several cases were previously reported in the literature.
Description:
We selected all RXTE observations of known transient black hole
binaries available in the archive from the start of the mission until
MJD 55601 (2011 February 9), concentrating on the data from the
Proportional Counter Array (PCA) instrument. We analysed 22 sources,
for a total of 7108 observations.
