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 2023, there are 17 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
NGC 1534 .

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.
