Query: Possible hot spots excited by the relativistic jets of Cygnus X-3   We present the results of a deep search for associated radio features in the
vicinity of the microquasar Cygnus X-3. The motivation behind is to find out
evidence for interaction between its relativistic jets and the surrounding
interstellar medium, which could eventually allow us to perform calorimetry of
the total energy released by this microquasar during its flaring lifetime.
Remarkably, two radio sources with mJy emission level at centimeter wavelengths
have been detected in excellent alignment with the position angle of the inner
radio jets. We propose that these objects could be the hot spots where the
relativitic outflow collides with the ambient gas in analogy with
Fanaroff-Riley II radio galaxies. These candidate hot spots are within a few
arc-minutes of Cygnus X-3 and, if physically related, the full linear extent of
the jet would reach tens of parsecs. We discuss here the evidence currently
available to support this hypothesis based on both archival data and our own
observations.
