The collimation in the twin jet of NGC 1052

09 February 2022

The radio galaxy NGC 1052 has been explored in the innermost regions of its dual jet by means of radio interferometr.  An international team of radio astronomers led by Dr. Anne-Kathrin Baczko from our institut shows  that the jet presents a clear transition in the collimation profile at 10 000 gravitational radii, with an upstream parabolic shape, which turns into conical downstream.  At about 1 000 gravitational radii, the jet has an opening angle of about 30°.  These results show that the approaching (eastern) and receding (western) show a somewhat different emission, for which the receding jet emission my be affected by an absorption cloud of gas in the line of sight.  More information is available at the original publication in the journal Astronomy & Astrophysics, available here
