The math relevant to OP is accessible via the second link in the text: https://arxiv.org/pdf/2508.21748 I guess you might have to follow some citations too. But we were on a tangent about white holes, which would be unreasonable to expect in the article. I and the other reply have already told you where to find that math.

Naive outsider here... The "single naked" titling is a bit misleading, since there are hundreds of these challenging current theory. But how often are those we do see are replicated in the so-call smear of lensing? Does this instance (QSO1) presenting 3 times create more analysis opportunities? E.g., the 7.3-hour observation that produced higher-resolution data that checked out as a vortex of hydrogen: would we expect to see the same features in all three images (modulo lensing transforms)? Reading that preprint (at [1]), it seemed they only used 1 of 3 (image A). [1] preprint…
