List of spiral DRAGNs

Last updated

Spiral DRAGNs or Speca-like galaxies are a type of spiral galaxies which are also radio galaxies or which contain DRAGNs (Double Radio-source Associated with Galactic Nucleus).

Contents

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 2024, there are nearly 36 spiral DRAGNs. [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] Nearby Seyfert galaxies containing small or galaxy-scale radio jets/lobes are not accepted as Specas or Spiral DRANGs.

GalaxyIdentified DateNotesReferences
galaxy 0313-192 1998First known spiral DRAGN, located in Abell 428. It is the first spiral DRAGN with VLBI detection. [8] [9] [10] [11]
Speca 2011First confirmed case due to its episodic radio jet nature. Hosted in a massive spiral and with giant Mpc-scale radio-lobes. It was the second galaxy shown to have three episodes of periodic activity, the first was an elliptical. [NB 1] [12] [13] [10]

SDSS J1649+2635 2014Fourth 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] [15] [10] [16]

J1159+58202012/2015Candidate: Disturbed galaxy with signs of a merger. [18] [17]
J1352+31262015Candidate: Galaxy was well studied at the time of the discovery by Singh et al. The galaxy was classified as spiral or irregular galaxy. [17]
MCG+07-47-102016radio source has a low luminosity [19]
J0354-13402022spiral host that is a narrow-line Seyfert 1, size of the de-projected jets is 250 kpc [20]
J0209+07502022loose spiral arms, has star-forming clumps [21]
J0806+06242022several spiral arms and a luminous bar-like feature [21]
J1328+57102022low-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. [21]
J1656+64072022extremely massive star-forming spiral galaxy [21]
J1128+24172022star-forming clumps in the arms [21]
J1646+3832022dust-lane with peculiar arc-like shape [21]
