| Abstract |
We present the results of the analysis of two Chandra observations of
Circinus X-1 performed in 2007, for a total exposure time of ~50 ks. The
source was observed with the High Resolution Camera during a long X-ray
low-flux state of the source. Cir X-1 is an accreting neutron star
binary system that exhibits ultra-relativistic arcsec-scale radio jets
and an extended arcmin-scale radio nebula. Furthermore, a recent paper
has shown an X-ray excess on arcmin-scale prominent on the side of the
receding radio jet. In our images, we clearly detect X-ray structures on
both the side of the receding and the approaching radio jet. The X-ray
emission is consistent with a synchrotron origin. Our detection is
consistent with neutron star binaries being as efficient as black hole
binaries in producing X-ray outflows, despite their shallower
gravitational potential. |
