List of spiral DRAGNs

Last updated

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.

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 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]
