Thanks! I saw three theories listed in the nature article and none of them mentioned lensing or Einstein rings.
Some curiosities behind the question were whether optical and radio frequencies behave the same with lensing. And how to tell if the radio image is in front of or behind the stars.
I'm an armchair astronomer if that, and obviously didn't read the source paper. Appreciate your thoughtful response!
