Probing the polarization characteristics of SS433 on mas scales
Abstract
We present a status report of dedicated circular polarization (CP) global VLBI observations of SS433. The total intensity image of the source is presented. We do not detect linear polarization in the core region of the source. We estimate the errors in D-terms for the EVN, and its effect on the final right-left circular polarization gain calibration. The data from this and earlier observations are analyzed with the "zero-V" self-calibration technique, in order to obtain indications for detectable CP in different regions of the source. Our data show no evidence for strong gyro-synchrotron (GS) emission on the size scale probed by our beam.
