Hard evidence for quasar lensing

AI Thread Summary
The discussion centers on the need for definitive evidence of quasar lensing, specifically seeking irrefutable correlations in light curves and morphological similarities, such as corresponding jets, in lensed quasars. The original poster emphasizes the importance of clear, mirror-image characteristics in images of these quasars, rather than just the presence of jets, which can be common among many quasars. A response questions the clarity of the original request, asking whether the focus is on evidence for quasar lensing or its effects on background objects. The conversation highlights the challenge of finding unequivocal data to support these claims. Overall, the quest for solid proof of quasar lensing remains a key focus in the discussion.

Hello, could someone point out to me

1) Ironclad evidence of correlated light curves - and I mean a correlation that is beyond doubt - among lensed quasars

2) Morphological correspondence - e.g. corresponding jets - in images of lensed quasars.

I can find sketchy cases which may be correlated, but I would like to see direct and incontrovertible evidence of both light curve correlation that leaves no doubt, and mirror image morphology of the images.

Thanks in advance!

PS - just because two quasars have jets does not mean much, as jets may be characteristic of many if not all quasars. A real case of interest would be clearly mirror-imaged isophotes of the two images.

What exactly is a "correlated light curve"?

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
