Rapid variability of the kHz-QPO frequency in 4U1608-52
S. Paltani, D. Barret, J. F. Olive +1
We investigate the variability of the QPO frequency in 4U1608-52 on very short time scales of a few seconds. We detect changes in frequency as fast as 0.5 Hz/s, which is more than…
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…
The INTEGRAL View of the Galactic Nucleus
A. Goldwurm, G. Belanger, P. Goldoni +15
We present the preliminary results of the observational campaign performed in 2003 to study the Galactic Nucleus with INTEGRAL. The mosaicked images obtained with the IBIS/ISGRI co…
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…
