Low and High Angular Momentum Accretion Flows in BHCs: Case Study of XTE J1550-564
Roberto Soria, Kinwah Wu, Diana Hannikainen +2
The 1998 outburst of XTE J1550-564 started with a hard X-ray spike, rising in less than a day and declining after 3-4 days; at the same time, the soft X-ray flux was rising with a…
The transient X-ray source SAX J2239.3+6116 and its optical counterpart
J. J. M. in 't Zand, J. Halpern, M. Eracleous +4
We have discovered with the Wide Field Cameras on board BeppoSAX the weak transient X-ray source SAXJ2239.3+6116 whose position coincides with that of 4U2238+60/3A2237+608 and is c…
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…
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…
