Linear radio structures in selected Seyfert and LINER galaxies
Abstract. High resolution MERLIN 5 GHz observations (0 ′′ . 04) of 7 Seyfert galaxies, selected as the ones previously showing evidence of collimated ejection, have been compared with high resolution archive HST data. The radio maps reveal rich structures in all the galaxies. NGC 2639 and TXFS 2226-184 have multiple knot parsec-scale extended structures, Mrk 1034, Mrk 1210, NGC 4922C and NGC 55...
متن کاملOptical Properties of Radio-selected Narrow Line Seyfert 1 Galaxies
We present results from the analysis of the optical spectra of 47 radio-selected narrow-line Seyfert 1 galaxies (NLS1s). These objects are a subset of the First Bright Quasar Survey (FBQS) and were initially detected at 20 cm (flux density limit ∼ 1 mJy) in the VLA FIRST Survey. We run Spearman rank correlation tests on several sets of parameters and conclude that, except for their radio proper...
متن کاملSeyfert Galaxies: Nuclear Radio Structure and Unification
We have observed a sample of Seyfert (Sy) galaxies with the global Very Long Baseline Interferometry (VLBI) to test the predictions of the unification scheme for the Sy galaxies which hypothesises that Sys of Type 1 and of Type 2 constitute a single population of objects. If Sy 1 and Sy 2 galaxies differ only in the orientation of the axisymmmetric active nucleus with respect to the observer, t...
متن کاملRadio Continuum Morphology of Southern Seyfert Galaxies ⋆
We present radio observations for 29 southern Seyfert galaxies selected from a volume limited sample with cz < 3600 km s −1 , and declination δ < 0 •. Objects with declination −30 • < δ < 0 • were observed with the Very Large Array (VLA) at 6 cm (4.9 GHz) and objects with δ < −30 • were observed with the Australia Telescope Compact Array (ATCA) at 3.5 cm (8.6 GHz). Both the VLA and the ATCA obs...
متن کاملParsec-scale radio structures in the nuclei of four Seyfert galaxies
We present 18-cm radio maps of four Seyfert nuclei, Mrk 1, Mrk 3, Mrk 231 and Mrk 463E, made with the European VLBI Network (EVN). Linear radio structures are present in three out of four sources on scales of ∼100 pc to ∼1 kpc, and the 20-mas beam of the EVN enables us to resolve details within the radio structures on scales of < 10 pc. Mrk 3 was also imaged using MERLIN and the data combined w...
