A Radio U-Net pipeline produces pixel-level segmentation maps and probability scores for diffuse radio emission in 3822 galaxy clusters from LoTSS-DR3, yielding a high-confidence sample of 357 and confirming trends with mass and redshift.

J1248+4826 is a newly identified compact ORC candidate with a ~30 kpc ring radius and ~200 kpc total extent at assumed z=0.2, consistent with the ORC population but with the host galaxy on the ring edge and no ongoing AGN activity.
The LOFAR DR3 survey yields 18 odd radio circles, confirming their rarity, heterogeneity, association with large ellipticals, and a relation where smaller ORCs avoid steep spectra.
FRIIs show lower cluster association rates than FRIs (30.6% vs 48.6% volume-limited; 32.6% vs 45.6% paired), with the gap widening at high luminosity, yet similar environments once inside clusters.
