Galaxy Interaction and Starburst-seyfert Connection
Galaxy interactions are studied in terms of the starburst-Seyfert connection. The starburst requires a high rate of gas supply. Since the efficiency for supplying the gas is high in a galaxy interaction, although the companion is not necessarily discernible, Seyfert galaxies with circumnuclear starbursts are expected to be interacting. Since the large amounts of circumnuclear gas and dust obscu...
متن کاملEvolution of a radio jet in a Seyfert galaxy
A very detailed monitoring of a radio flare in the Seyfert I galaxy III Zw 2 with the VLA and the VLBA is presented. The relative astrometry in the VLBA observations was precise on a level of a few μas. Spectral and spatial evolution of the source are closely linked and these observations allowed us to study in great detail a textbook example of a synchrotron self-absorbed jet. We observe a pha...
متن کاملA Radio Study of the Seyfert galaxy Markarian 6: Implications for Seyfert life-cycles
We have carried out an extensive radio study with the Very Large Array on the Seyfert 1.5 galaxy Mrk 6 and imaged a spectacular radio structure in the source. The radio emission occurs on three different spatial scales, from ∼7.5 kpc bubbles to ∼1.5 kpc bubbles lying nearly orthogonal to them and a ∼1 kpc radio jet lying orthogonal to the kpc-scale bubble. To explain the complex morphology, we ...
متن کاملBeppoSAX discovery of a new Seyfert 2 galaxy: 1SAXJ2234.8-2541
In the present work we report the BeppoSAXserendipitous discovery of the type 2 AGN 1SAXJ2234.8-2541 in the MECS field of view when pointing at the Seyfert 2 galaxy NGC7314. The source is optical identified with the bright (mB=14.40) galaxy ESO533-G50 at redshift z=0.026. The source is clearly detected at energies above 4 keV but barely visible below this energy implying heavy obscuration intri...
متن کاملDiscovery of a Narrow-Line Seyfert 1 galaxy
We have discovered a Narrow-Line Seyfert 1 (NLS1) galaxy and identified it with an ultrasoft X-ray source (RX 215319-1514) detected with ROSAT . We present its X-ray and optical spectral characteristics. Its redshift is found to be 0.0778±0.0002. Its optical spectrum shows fairly strong Fe II emission lines, and its X-ray spectrum has an extremely steep power-law index of Γ ≥4, making it an ext...
