List of spiral DRAGNs

From Wikipedia, the free encyclopedia

Spiral DRAGNs are a type of galaxy; spiral galaxies which contain DRAGNs (Double Radio-source Associated with Galactic Nucleus), and are therefore also radio galaxies.

Most DRAGNs are associated with elliptical galaxies, as are most double-lobed radio-galaxies.[1] Spiral DRAGNs are inconsistent with currently known galaxy formation processes.[2] As of 2016, there are 6 known spiral DRAGNs that are widely accepted.[3]

Lenticlular galaxies containing DRAGNs are as rare as spiral DRAGNs, with only 5 known examples as of 2020,[4] including: Centaurus A,[5][6] NGC 612[7] and .[4]

Galaxy Identified Date Notes
galaxy 0313-192 2003 First known spiral DRAGN, located in . It is the first[8] spiral DRAGN with VLBI detection. [9][10]
2011 Second known spiral DRAGN. It was the second galaxy shown to have three episodes of periodic activity, the first was an elliptical. [NB 1][11][10]
J2345-0449 2014 Third known spiral DRAGN (found and studied first by Bagchi et al. 2014) with two episodic activities, observed at radio wavelengths and measuring about 1.6 Megaparsecs in total size.
2014 Fourth known spiral DRAGN; first located in a grand design spiral galaxy. It was discovered by cross-matching spiral galaxies identified by galaxy zoo volunteers with the Unified Radio Catalog. It was the first systematic search for spiral DRAGNs. [1][12][10][13]
J0836+0532 2015 Two clear spiral arms [14]
J1159+5820 2012/2015 Candidate: Disturbed galaxy with signs of a merger. [15][14]
J1352+3126 2015 Candidate: Galaxy was well studied at the time of the discovery by Singh et al. The galaxy was classified as spiral or irregular galaxy. [14]
MCG+07-47-10 2016 radio source has a low luminosity [3]
