SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
Integral observation of Cyg X-1 in an intermediate state
J. Malzac, P. O. Petrucci, E. Jourdain +11
We present preliminary results of an observation of Cygnus X-1 with INTEGRAL performed on June 7-11 2003. Both spectral and variability properties of the source indicate that Cygnu…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: sky distribution
G. Weidenspointner, V. Lonjou, J. Knoedlseder +14
During its first year in orbit the INTEGRAL observatory performed deep exposures of the Galactic Center region and scanning observations of the Galactic plane. We report on the sta…
GRS 1915+105: The first three months with INTEGRAL
D. C. Hannikainen, O. Vilhu, J. Rodriguez +19
GRS 1915+105 is being observed as part of an Open Time monitoring program with INTEGRAL. Three out of six observations from the monitoring program are presented here, in addition t…
RXTE Observations of the Microquasar GRS 1915+105
J. Rodriguez, P. Durouchoux, M. Tagger
We analyse a set of three RXTE Target of Opportunity observations of the Galactic microquasar GRS 1915+105, observed in April 2000. We concentrate on the timing properties of the s…
The Accretion Ejection Instability : Observationnal Tests
J. Rodriguez, P. Varniere, M. Tagger +1
The Accretion Ejection Instability (hereafter AEI), has been proposed to explain, the energy and angular momentum transport from the innermost parts of accretion disks in the X-Ray…
