Description
A subset of microquasars exhibits high peculiar velocity with respect to
the local standard of rest due to the kicks they receive when being born
in supernovae. The interaction between the radio plasma released by
microquasar jets from such high-velocity binaries with the interstellar
medium must lead to the production of trails and bow shocks similar to
what is observed in narrow-angle tailed radio galaxies and pulsar wind
nebulae. We present a set of numerical simulations of this interaction
that illuminate the long-term dynamical evolution and the observational
properties of these microquasar bow-shock nebulae and trails. We find
that this interaction always produces a structure that consists of a bow
shock, a trailing neck, and an expanding bubble. Using our simulations
to model emission, we predict that the shock surrounding the bubble and
the neck should be visible in Hα emission, the interior
of the bubble should be visible in synchrotron radio emission, and only
the bow shock is likely to be detectable in X-ray emission. We construct
an analytic model for the evolution of the neck and bubble shape and
compare this model with observations of the X-ray binary SAX
