Hard evidence for quasar lensing

Click For Summary
SUMMARY

The discussion centers on the need for definitive evidence of quasar lensing, specifically seeking ironclad proof of correlated light curves and morphological correspondence in lensed quasars. The user emphasizes the requirement for direct and incontrovertible evidence, particularly mirror-imaged isophotes, rather than mere correlations that could be coincidental. The conversation highlights the complexity of establishing such evidence in astrophysics, particularly in distinguishing between genuine lensing effects and characteristics common to quasars.

PREREQUISITES
  • Understanding of quasar properties and behavior
  • Familiarity with gravitational lensing concepts
  • Knowledge of light curve analysis techniques
  • Experience with astrophysical imaging and morphology
NEXT STEPS
  • Research methods for analyzing quasar light curves in detail
  • Study gravitational lensing effects on astrophysical objects
  • Explore techniques for identifying morphological correspondence in astronomical images
  • Investigate case studies of confirmed lensed quasars
USEFUL FOR

Astronomers, astrophysicists, and researchers interested in gravitational lensing phenomena and the study of quasars will benefit from this 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"?
