BATSE observations of BL Lac Objects
V. Connaughton, C. R. Robinson, M. L. McCollough +1
The Burst and Transient Source Experiment (BATSE) on the Compton Gamma-Ray Observatory has been shown to be sensitive to non-transient hard X-ray sources in our galaxy, down to flu…
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…
The X-ray Behavior of Two CVs: TT Ari and DP Leo
Craig R. Robinson, France A. Cordova
We present ROSAT PSPC observations of the nova-like, or intermediate polar, TT Ari and the eclipsing polar DP Leo. Observations of TT Ari were performed as part of a simultaneous m…
