A new cosmic high energy accelerator from keV to TeV
INTEGRAL has discovered, using the IBIS instrument, a new gamma-ray
source (IGR J18135-1751). This source is remarkable, since it
coincides spatially with one of the ten objects which have been seen
during the first survey at TeV energies of the inner part of the
galaxy: HESS J1813-178. This source is a powerful ultra-high energy
emitter in the 0.2-10 TeV range. The X-ray counterpart
(AGPS273.4-17.8) of the INTEGRAL source has an absorbed spectrum and
is thought to be either a pulsar wind nebula or a supernova remnant.
This picture shows the IBIS/ISGRI 20-100 keV image of IGR J18135-1751
as well as the position of HESS J1813-178 (green circle) and
AGPS273.4-17.8 (white cross). The white spot on the left is the
saturated image of the bright LMXB GX 13+1.
