INTEGRAL and XMM-Newton observations towards the unidentified MeV source GRO J1411-64
Diego F. Torres, Shu Zhang, Olaf Reimer +9
The COMPTEL unidentified source GRO J1411-64 was observed by INTEGRAL, and its central part, also by XMM-Newton. The data analysis shows no hint for new detections at hard X-rays.…
Are Ti44-Producing Supernovae Exceptional?
L. -S. The, D. D. Clayton, R. Diehl +6
According to standard models supernovae produce radioactive Ti, which should be visible in gamma-rays following decay to Ca for a few centuries. $^{44}Ti production i…
COMPTEL Observations of the Gamma-ray Blazars 3C~454.3 and CTA 102 During the CGRO Mission
S. Zhang, W. Collmar, V. Schonfelder
We have investigated the MeV behaviour of the \gray blazars 3C~454.3 and CTA 102 by analyzing all COMPTEL observations of this sky region during the complete CGRO mission. Both sou…
Al(26) Studies with INTEGRAL's Spectrometer SPI
R. Diehl, K. Kretschmer, G. Lichti +13
Al(26) radioactivity traces recent nucleosynthesis throughout the Galaxy, and is known to be produced in massive stars and novae. The map from its decay gamma-ray line suggests mas…
COMPTEL Observations of the Blazar PKS 1622-297 during a Gamma-Ray High State in 1995
S. Zhang, W. Collmar, V. Schonfelder +6
PKS 1622-297 was detected as a source of gamma-rays by the EGRET experiment at energies above 100 MeV during a gamma-ray outburst June and July 1995. We analyzed the COMPTEL data (…
Possibility of the detection of classical novae with the shield of the INTEGRAL-spectrometer SPI
P. Jean, J. Gomez-Gomar, M. Hernanz +7
The shield of the INTEGRAL spectrometer provides a large detection area with a wide field-of-view. Calculations have been performed to check whether the temporal analysis of the co…
