Integral’s view of X-ray nova IGR J17497-2821

This animation consists of a sequence of two images taken by the IBIS/ISGRI instrument on board ESA’s Integral gamma-ray observatory, and it shows the galactic centre region in hard X-rays.

In one frame, the bright X-ray nova IGR J17497-2821 (indicated by the arrow) is seen during its discovery outburst, while the other frame is the same field as observed prior to the nova event. The other variable sources are well known X-ray binaries.
