摘要：Cygnus X-3 is a well know microquasar which shows state changes, strong radio emission, hard
X-ray/X-ray/radio correlations, and relativistic jets. The exact nature of the compact object associated
with this system is still uncertain. In this presentation are shown new results which will
further illustrate the complexity and uniqueness of this system.
In 2003, using Chandra observations, extended X-ray emission was discovered associated with
Cygnus X-3 [3]. The most promising interpretation of this feature was that it is a jet impact
region. In 2006 a longer Chandra observation during which Cygnus X-3 was in a brighter X-ray
state has revealed a much better look at this emission. Even though this feature is 16′′ away from
Cygnus X-3 it demonstrates remarkable time correlated activity associated with Cygnus X-3. The
behavior of this emission and the possible nature of this feature will be discussed.
