Identification of the Periodic Hard X-Ray Transient GRO J1849-03 with the X-Ray Pulsar GS 1843-02 = X1845-024 - a New Be/X-Ray Binary
P. Soffitta, J. A. Tomsick, B. A. Harmon +5
We identify the periodic transient hard X-ray source GRO J1849-03 with the transient x-ray pulsar GS 1843-02 = X1845-024 based on the detection of x-ray outbursts from X1845-024 co…
Five Years in the Life of Cygnus X-1: BATSE Long-Term Monitoring
W. Paciesas, C. R. Robinson, M. L. McCollough +3
The hard X-ray emission from Cygnus X-1 has been monitored continually by BATSE since the launch of CGRO in April 1991. We present the hard X-ray intensity and spectral history of…
A Sequence of Declining Outbursts from GX339-4
B. C. Rubin, B. A. Haron, W. S. Paciesas +3
The flux and spectrum of the black hole candidate GX339-4 has been monitored by the Burst and Transient Source Experiment (BATSE) on the Compton Gamma-ray Observatory (CGRO) since…
Kilo-hertz QPO and X-ray Bursts in 4U 1608-52 in Low Intensity State
W. Yu, S. N. Zhang, B . A. Harmon +8
We present the results from RXTE/PCA observations of 4U 1608-52 in its island state on March 15, 18 and 22 of 1996. Three type I X-ray bursts were detected in one RXTE orbit on Mar…
Kilo-hertz QPO in Island State of 4U1608-52 as Observed with RXTE/PCA
W. Yu, S. N. Zhang, B . A. Harmon +8
We report RXTE/PCA observations of 4U 1608-52 on March 15, 18 and 22 immediately after the outburst in early 1996. The persistent count rates ranged from 190 to 450 cps (1-60 keV).…
Galactic Black Hole Binaries: Multifrequency Connections
S. N. Zhang, I. F. Mirabel, B. A. Harmon +4
We review the recent multifrequency studies of galactic black hole binaries, aiming at revealing the underlying emission processes and physical properties in these systems. The opt…
