A Study of SS-433 at TeV Energies with the HEGRA CT-System

We present preliminary results of a search for TeV γ-ray emission from the Galactic microquasar/supernova remnant SS-433/W50. The HEGRA CT-System observed SS-433 for a total of ∼55 hrs with various locations in the field of view considered as possible TeV sources. The jets of SS-433 make it potentially one of the most powerful accelerators of cosmic rays in our galaxy, and a particularly interesting site is a possible termination shock region ∼ 1.0° east of SS-433, where cosmic ray acceleration may be taking place. The upper limit for TeV emission from this region constrains the shock-compressed magnetic field when interpreted in the synchrotron/inverse Compton framework.
