摘要
The gamma-ray blazar 1611+343 was observed with polarization VLBI mode at 5 GHz in February 1999. The total intensity (I) VLBI image of the source shows a core-jet structure. The jet bends eastward at - 3 mas south of the core. Four components have been detected from results of fitting, with apparent speeds estimated at 6.7 ±0.7, 2.5 ±0.3, 4.5 ±0.5 h-1c for three jet components (taking H0 = 100 h km s-1 Mpc-1, q0 = 0.5). The polarization (P) VLBI image of 1611+343 displays the polarized configuration in the jet. The mechanism of the curved jet is discussed.
