|The Herschel far-infrared view of a shell bubble inflated by Cygnus X-1 microquasar jets
|Radio lobes and hotspots provide invaluable diagnostics of the relativistic jet power and content in active galactic nuclei. Likewise, the interstellar medium should behave like a calorimeter for microquasar jets. However, signatures of the interaction of microquasar jets with the ISM are both fainter and on comparatively larger scales than for AGN jets. We propose here far-infrared (FIR) Herschel-PACS and SPIRE wide-field imaging observations to map the surrounding environment of the microquasar and supergiant X-ray binary Cygnus X-1. This will allow us to detect the presence of filamentary structures associated with shell shock ionisation. Measuring the shell distribution, size and speed will constrain the average jet power and provide information on the fraction of the accretion power dissipated by ejection instead of radiation. These observations, by bringing a case study of shock collisions of relativistic jets with the ISM, close to a star formation region, and potentially triggering star forming processes, will strongly contribute to the Herschel legacy.

|Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
