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…
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…
New determinations of gamma-ray line intensities of the Ep = 550 keV and Ep = 1747 keV resonances of the 13-C(p,gamma)14-N reaction
J. Kiener, M. Gros, V. Tatischeff +10
Gamma-ray angular distributions for the resonances at Ep = 550 keV and 1747 keV of the radiative capture reaction 13-C(p,g)14-N have been measured, using intense proton beams on is…
On the optical extinction and distance of GRS 1915+105
C. Chapuis, S. Corbel
Based on new millimeter and radio observations, we reevaluate the total hydrogen column density along the line of sight to the microquasar GRS 1915+105 to NH=(3.5 +/- 0.3) 10^22 cm…
The Distance to the Soft Gamma Repeater SGR 1627-41
S. Corbel, C. Chapuis, T. M. Dame +1
We report millimeter observations of the line of sight to the recently discovered Soft Gamma Repeater, SGR 1627-41, which has been tentatively associated with the supernova remnant…
Near-Infrared Photometry of Blazars
C. Chapuis, S. Corbel, P. Durouchoux +2
Two days of observations were conducted at the Palomar Observatory during the nights of 25 and 26 February 1997 with the Hale telescope, in order to search for rapid variability in…
