INTEGRAL/XMM views on the MeV source GRO J1411-64
Diego F. Torres, Shu Zhang, Olaf Reimer +9
The COMPTEL unidentified source GRO J 1411-64 was observed by INTEGRAL and XMM-Newton in 2005. The Circinus Galaxy is the only source detected within the 4 location error of GRO…
XMM detection of the supernova remnant G337.2+0.1
Jorge A. Combi, Juan F. Albacete Colombo, Gustavo E. Romero +1
We report the first XMM detection of the SNR candidate G337.2+0.1 (=AX J1635.9-4719). The object shows centrally filled and diffuse X-ray emission. The emission peaks in the hard 3…
Extremely violent optical microvariability in blazars: fact or fiction?
Sergio A. Cellone, Gustavo E. Romero, Anabella T. Araudo
Variability amplitudes larger than 1 magnitude over time-scales of a few tens of minutes have recently been reported in the optical light-curves of several blazars. In order to ind…
On the multiwavelength spectrum of the microquasar 1E 1740.7-2942
V. Bosch-Ramon, G. E. Romero, J. M. Paredes +3
Context. The microquasar 1E 1740.7-2942 is a source located in the direction of the Galactic Center. It has been detected at X-rays, soft gamma-rays, and in the radio band, showing…
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.…
Leptonic emission from microquasar jets: from radio to very high-energy gamma-rays
V. Bosch-Ramon, J. M. Paredes, G. E. Romero
Microquasars are sources of very high-energy gamma-rays and, very probably, high-energy gamma-ray emitters. We propose a model for a jet that can allow to give accurate observation…
