| Research Abstract |
We conducted the first systematic VLBI studies of broad-absorption line quasars and narrow-line Seyfert1galaxies, which are believed to be driven by rapidly growing supermassive black holes. Our unique approach from radio observations at unprecedented angular resolutions has provided very crucial results about the vicinity of these black hole systems. The results impact the current pictures of relativistic jets, outflows, and their inclinations and ages of active galactic nuclei on an evolutionary phase.
