BeppoSAX Observations of the galactic source GS1826-238 in a hard X-ray high state
Stefano Del Sordo, Filippo Frontera, Elena Pian +7
The BeppoSAX Narrow Field Instruments observed the galactic source GS1826-238 in October 1997, following a hard X-ray outburst with a peak flux of about 100 mCrab detected by BATSE…
Galactic Superluminal Sources
B. A. Harmon
A new class of X-ray sources was clearly established with the discovery of highly relativistic radio jets from the galactic sources GRS 1915+105 and GRO J1655-40. Both of these obj…
X-Ray Spectral Behavior of the Relativistic Jet Source Cygnus X-3
M. L. McCollough, C. R. Robinson, S. N. Zhang +13
Cyg X-3 is an unusual X-ray binary which shows remarkable correlative behavior between the hard X-ray, soft X-ray, and the radio. We present an analysis of these long term light cu…
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).…
Long-Term Variability in Bright Hard X-ray Sources: 5+ Years of BATSE Data
C. R. Robinson, B. A. Harmon, M. L. McCollough +6
The operation of CGRO/BATSE continues to produce, after more than 5 years, a valuable database for the study of long-term variability in bright hard X-ray sources. The all-sky capa…
Radio, Infrared and X-ray observations of GRS 1915+105
R. P. Fender, G. G. Pooley, C. R. Robinson +3
We present multiwavelength observations of the superluminal jet source GRS 1915+105 in 1996 April-May, over which period a variety of phenomena, including radio QPO, strong infrare…
