An Unusual Radio Galaxy in Abell 428: A Large, Powerful FR I Source in a Disk-dominated Host

  author={Michael J. Ledlow and Frazer N. Owen and William C. Keel},
  journal={The Astrophysical Journal},
We report the discovery of a powerful (~1024 h−275 WHz−1 at 20 cm) FR I radio source in a highly flattened disk-dominated galaxy. Half the radio flux from this source is concentrated within the host galaxy, with the remainder in a pair of nearly symmetrical lobes of total extent ~200 kpc nearly perpendicular to the disk. Traditional wisdom maintains that powerful, extended radio sources are found only in ellipticals or recent merger events. We report B, R, J, and K imaging, optical spectroscopy…

A Large-Scale Jet and FR I Radio Source in a Spiral Galaxy: The Host Properties and External Environment
We have identified a large (≈200 h kpc), powerful double radio source whose host galaxy is clearly a disk and most likely a spiral. This FR I-like radio galaxy is located very near the center of the
The Spiral Host Galaxy of the Double Radio Source 0313-192
We present new Hubble Space Telescope (HST), Gemini South, and Chandra observations of the radio galaxy 0313-192, which hosts a 350 kpc double source and jets, even though previous data have
PKS 1814-637: a powerful radio-loud AGN in a disk galaxy
We present a detailed study of PKS 1814-637, a rare case of powerful radio source (P5 GHz = 4.1 × 1025 W Hz-1) hosted by a disk galaxy. Optical images have been used to model the host galaxy
Discovery of a spiral-host episodic radio galaxy
We report the discovery of a unique radio galaxy at z = 0.137, which could possibly be the second spiral-host large radio galaxy and also the second triple–double episodic radio galaxy. The host
The disc-dominated host galaxy of FR-I radio source B2 0722+30
We present new observational results that conclude that the nearby radio galaxy B2 0722+30 is one of the very few known disc galaxies in the low-redshift Universe that host a classical double-lobed
Central Activity in the Barred Galaxy NGC 3367
We report the radio continuum structure of the barred galaxy NGC 3367 with an angular resolution of ~45. The radio structure indicates emission from the disk and from a triple source consisting of
PKS B1400-33: an unusual radio relic in a poor cluster
We present new arcminute resolution radio images of the low surface brightness radio source PKS B1400-33 that is located in the poor cluster Abell S753. The observations consist of 330 MHz VLA, 843
The remnant radio galaxy associated with NGC 1534
Abstract We present new observations of the large-scale radio emission surrounding the lenticular galaxy NGC 1534 with the Australia Telescope Compact Array and Murchison Widefield Array. We find no
Rare Finding of a 100 Kpc Large, Double-lobed Radio Galaxy Hosted in the Narrow-line Seyfert 1 Galaxy SDSS J103024.95+551622.7
Among the large varieties of active galactic nuclei (AGN) known, narrow line Seyfert 1 (NLSy1) galaxies are a puzzling class, particularly after the discovery of $\gamma$-ray emission in a handful of
The radio-loud narrow-line Seyfert 1 galaxy 1H 0323+342 in a galaxy merger
The supermassive black holes (SMBHs) of narrow-line Seyfert 1 galaxies (NLS1s) are at the lower end of the mass function of active galactic nuclei (AGNs) and reside preferentially in late-type host


The nature of the extended emission features in IRAS 04210+0400
The IRAS source 04210+0400 coincides with a galaxy that exhibits strong double-lobed radio emission extending 15 kpc outside the optical galaxy. New high-resolution radio maps reveal a classical
