Abstract
We present observations of the outflowing shockwave north of the
microquasar (X-ray binary with jets), Cygnus X-1. We use Westerbork
Synthesis Radio, Chandra X-ray, and WIYN Hydra optical spectroscopic
observations to probe the limb-brightened shell where the jet of the
microquasar seems to be driving a parsec-scale shock into a nearby HII
region. In particular, the unique ability of WIYN-Hydra to place fibers
in specified positions in between stars in a relatively crowded, large
field on the sky makes it a powerful instrument for carrying out these
observations. We then compare our multiwavelength observations to the
detailed MAPPINGSIII shock models to place the most robust constraints
to date on the density and velocity of the outflow and the power needed
to drive it. Our analysis of the jet driven outflow from this
microquasar leads us to revisit our understanding of dominant physical
mechanisms involved in jet-driven, parsec-scale shocks in the ISM.
