SPI energy calibration
V. Lonjou, J. Knodlseder, J. P. Roques +7
The status of the SPI energy calibration after the first year of INTEGRAL operations is reported. We have studied the gain variations and we have demonstrated that the most importa…
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…
Search for 44Ti gamma-ray line emission from GRO J0852-4642 with INTEGRAL/SPI
A. von Kienlin, D. Attie, S. Schanne +7
The gamma-ray source GRO J0852-4642, discovered by COMPTEL, is a possible counterpart of the supernova remnant RX J0852-4622. Detection of radioactive decay from 44Ti nuclei would…
The INTEGRAL/SPI response and the Crab observations
P. Sizun, C. R. Shrader, D. Attie +8
The Crab region was observed several times by INTEGRAL for calibration purposes. This paper aims at underlining the systematic interactions between (i) observations of this referen…
SPI/INTEGRAL observation of 1809 keV gamma-ray line emission from the Cygnus X region
J. Knödlseder, M. Valsesia, M. Allain +10
We present first results on the observation of 1809 keV gamma-ray line emission from the Cygnus X region with the SPI imaging spectrometer. Our analysis is based on data from the p…
