SS-433/W50 at TeV Energies

The HEGRA CT-System was used to search for TeV gammarays from the microquasar and supernova remnant combination SS433/W50 over the 1998 and 1999 observing seasons, resulting in about 20 hours of useful data. An analysis of various extended sources of location guided by X-Ray observations reveals no evidence for TeV emission at photon energies above 1 TeV, with resulting 99% upper limits in the range 8 to 10% of the Crab flux. For one of these locations, the eastern jet termination, a model predicting a presently detectable TeV gamma-ray flux via the inverse Compton upscattering of microwave background photons is now somewhat constrained. The results and model contraints are briefly discussed.
