Overview

• The overlapping rings in RAD J131346.9+500320 each span roughly one million light-years within a diffuse radio region about 2.6 million light-years across.
• Its radio luminosity is measured at about 2.27×10^26 W/Hz, roughly 100 times higher than previously known ORCs.
• The team reports a galaxy at the rings’ intersection that emits radio waves, offering a potential link to the energy source.
• Two additional ring features tied to the termini of powerful radio jets in dense cluster environments point to jet or wind interactions with ambient plasma as a leading scenario, still unproven.
• The discovery uses LOFAR survey data and is reported in Monthly Notices of the Royal Astronomical Society, with follow-up multiwavelength observations needed to test formation models.
