a Cosmological ORC is assumed to be a perpendicular merged Dual Herbig Haro system with perpendicular Birkeland Currents and plasma rings.

Wikipedia:  In astronomy, an odd radio circle (ORC) is a very large (over 50 thousand times the diameter of our Milky Way ~ 3 Million Light-years) unexplained astronomical object that, at radio wavelengths, is highly circular and brighter along its edges.

What is the origin of Birkeland Current systems and white holes around stars and galaxies?

Below: Not only Galaxies but also Stars seem to are created by a dual set of small Black Holes, creating a comparable Birkeland Current system with a star in the center. and a planetary disc.

Conclusion . A star system is based on the same dual ( or more) Black Hole and Birkeland current systems as a Galaxy.

Below: The Dark Matter distribution around a galaxy, is indicating,  the remnants of former dual  GABHs (Galaxy Anchor Black Holes) and  central White holes of smaller merger galaxies. around the large galaxy.
