Abstract |
We analyzed the zero-order image of a 50 ks Chandra gratings observation
of Circinus X-1, taken in 2005 during the source's low-flux state.
Circinus X-1 is an accreting neutron star that exhibits
ultrarelativistic arcsecond-scale radio jets and diffuse arcminute-scale
radio jets and lobes. The image shows a clear excess along the general
direction of the northwestern counterjet, coincident with the radio
emission, suggesting that it originates either in the jet itself or in
the shock that the jet is driving into its environment. This makes
Circinus X-1 the first neutron star for which an extended X-ray jet has
been detected. The kinetic jet power that we infer is significantly
larger than the minimum power required for the jet to inflate the
large-scale radio nebula. |
