A VLBI survey of compact Broad Absorption Lines (BAL) quasars with BALnicity Index BI=0
M. Ceglowski, M. Kunert-Bajraszewska, C. Roskowinski
We present high-resolution observations, using both the European VLBI Network (EVN) at 1.7-GHz, and the Very Long Baseline Array (VLBA) at 5 and 8.4-GHz to image radio structures o…
Broad absorption line (BAL) quasars as a class of low luminosity AGNs
M. Kunert-Bajraszewska, M. Ceglowski, C. Roskowinski +1
Broad absorption lines seen in some quasars prove the existence of ionized plasma outflows from the accretion disk. Outflows together with powerful jets are important feedback proc…
Hybrid morphology radio sources - follow-up VLBA observations
Maciej Ceglowski, Marcin Gawronski, Magdalena Kunert-Bajraszewska
Hybrid sources that present FR I - like jet on the one side of the radio core and FR II - like on the other are rare class of objects that may posses key to understanding the origi…
30 GHz monitoring of broad absorption line (BAL) quasars
Maciej Ceglowski, Magdalena Kunert-Bajraszewska, Bogna Pazderska +1
Broad absorption line (BAL) quasars have been studied for over thirty years. Yet it is still unclear why and when we observe broad absorption lines in quasars. Is this phenomenon c…
CSS galaxy embedded within the core of a bright X-ray cluster
Maciej Ceglowski, Magdalena Kunert-Bajraszewska, A. Siemiginowska +2
We discovered an X-ray cluster in a recent pointed Chandra observation of the radio-loud compact-steep-spectrum source 1321+045 at the redshift of 0.263. 1321+045 is part of larger…
Orientation of the cores of hybrid morphology radio sources
Maciej Ceglowski, Marcin Gawronski, Magdalena Kunert-Bajraszewska
The FRI/FRII dichotomy is a much debated issue in the astrophysics of extragalactic radio sources. Study of the properties of HYbrid MOrphology Radio Sources (HYMORS) may bring cru…
