Astronomy:List of spiral DRAGNs

From HandWiki

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.[4]

J0209+0750 2022 loose spiral arms, has star-forming clumps [19]
J0806+0624 2022 several spiral arms and a luminous bar-like feature [19]
J1328+5710 2022 low-mass, low-redshift galaxy with many star-forming regions, at least two prominent arms and a strong bar. One of the few intermediate massive black holes (≤ 105 M☉) with a strong radio emission and the first with a double-lobed radio emission. [19]
J1656+6407 2022 extremely massive star-forming spiral galaxy [19]
J1128+2417 2022 star-forming clumps in the arms [19]
J1646+383 2022 dust-lane with peculiar arc-like shape [19]
J0326-0623 2023 two major spiral arms, scale of the radio lobes is 430 kpc [3]
J1110+0321 2023 scale of the radio lobes is 100 kpc [3]
J1134+3046 2023 scale of the radio lobes is 380 kpc [3]
