X-ray and soft gamma-ray behaviour of the Galactic source 1E 1743.1-2843
Abstract
The X-ray persistent source 1E 1743.1-2843, located in the Galactic Centre region, has been detected by all X-ray telescope above 2 keV, whereas it is not visible in the soft X-rays (i. e. Rosat) because of the high column density along the line-of-sight. Moreover, the nature of this source remains still unknown. The gamma-ray satellite INTEGRAL has long observed the Galactic Centre region in the framework of the Core Programme. We report on results of two years of INTEGRAL observations of 1E 1743.1--2843 detected for the first time in the soft gamma-ray band. Since the source does not show any evidence for strong variability, we present the broad-band spectral analysis using not simultaneous XMM-Newton observations.
