IBIS/ISGRI observations of the Galactic Centre Region

IBIS/ISGRI observations of the Galactic Centre Region

Satellite: INTEGRAL
Depicts: IBIS observations in four different energy bands

This is an animation of four IBIS/ISGRI mosaic images of the galactic centre region in four different energy bands: 20-40 keV, 40-60 keV, 60-80 keV and 80-100 keV. The sources become dimmer and dimmer at higher energies because the number of photons they release decreases from the lower energy X-rays to the higher energy gamma-rays. The total exposure time is of 5.7 Msec. The main sources are labelled in the lowest energy (20-40 keV) image. The majority of the visible sources are Large Mass X-ray Binaries.

The results are published in: Paizis et al., 2004, Proceedings of the 5th INTEGRAL Workshop "The INTEGRAL Universe".
