| Abstract: Markarian 3 is a nearby (z = 0.0135) Compton-thick Seyfert 2 galaxy hosting a 0.3 billion solar mass black hole. Its nuclear region exhibits multiple signatures of dynamical activity. The presence of S-shaped radio jets and [OIII] line emitting gas on parsec to sub-kiloparsec scales, together with double-peaked [OIII] and Hydrogen Balmer lines from HST/STIS spectroscopy, motivates the possibility of jet precession driven by the presence of a binary supermassive black hole in Mrk 3. We present results from new Very Long Baseline Array (VLBA) observations at 15 and 22 GHz probing the parsec-scale radio structure and placing new constraints on the origin of its S-shaped morphology. We place our results in the larger context of parsec-scale radio cores and jets in "radio-quiet" Seyfert galaxies. |
