AI Thread Summary
Gravitational lensing of light from accretion discs around black holes, particularly in Kerr and Schwarzschild metrics, is a significant area of study. The lensing effect is notably strong near the minimum inner radius of the accretion disc. For distant observers, the appearance of the accretion disc can be complex due to this lensing. Resources such as Google Scholar and the Astrophysics Data System (ADS) are recommended for finding relevant academic papers. These platforms provide access to detailed mathematical analyses and articles that can aid in research projects on this topic.

Actually i want know about the lensing of light from accretion disc around a black hole(kerr and schwarschild). Is the lensing is strong for radie near minimum inner radius of accretion disc.
I want know how the accretion disc will look like for a distant observer.

Can somebody give me some papers or articles for the question especilly for the final part.
I am doing a project on it. actually i need more mathematical stuff

I suggest that you google it.

I'd avoid Google, since you are after the details, unless maybe you use Google scholar. The best approach would be to use http://adsabs.harvard.edu/abstract_service.html" astrophysics journal article search engine. Almost all the hits you get will have a link to the free ArXiv version of the papers, so you don't have to have journal subscriptions to view them.

I put in 'kerr lensing disk' and got a bunch of papers that looked they might be relevant for you.

Hope that helps!

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
