Anyway, I have a detailed account of gravitational lensing, including extragalactic microlensing, in my [http://urn.nb.no/URN:NBN:no-2021 thesis]. There is a section on history that would be suitable for Wikipedia with a bit of editing. Feel free to grab anything from there, I would have submitted it myself, but I don't have the time.... Anyway, I had Sjur Refsdal on the committee and partly advising, and worked with Rudy Schild (whose page on the Twin Quasar is linked), so it has received a lot of scrutiny. Drop me a note on kk@kjernsmo.net if somebody wants the LaTeX source (it's fairly clean). -- Kjetil Kjernsmo |

Revision as of 06:27, 1 July 2005
Draft for missing parts:
- note about famous un-scientific experiment
- Missing: light refraction/optical lenses/gravitational lenses
- Missing: not only visible light but generaly any radiation
- Missing: info about the weakness of this effect
- Missing: schema
- Missing: images
- Astronomical Applications
- Magnification -> study the source of the light
- Another use of these lensing systems is the study of the distribution of masses that are doing the deflection.
- This is a (classic) inverse problem: what distribution of masses can distort the light of a distant source into the picture I see in my telescope?
- Indirect method to study theses objects which may be indetectable by others means. These results may provide an estimate of the amount of dark matter there is in the Universe.

- Now covered astronomical applications, and the way it affects any radiation. EddEdmondson 11:44, 31 Mar 2004 (UTC)
I can't understand what the top diagram represents. Some text in the caption is badly needed so can some kind person add some, please. For example, what's the golden ball in the middle? I've put the pic here until some is written. Thanks,

I agree with Adrian that the depiction is more confusing than clarifying, I would suggest removing the galaxy cluster for clarity.
