Discussion Overview
The discussion centers on the gravitational lensing of light from accretion discs around black holes, specifically focusing on the Kerr and Schwarzschild solutions. Participants explore the strength of lensing near the minimum inner radius of the accretion disc and how these discs appear to distant observers. There is a request for mathematical resources and papers related to this topic.
Discussion Character
- Exploratory, Technical explanation, Homework-related
Main Points Raised
- One participant inquires about the strength of gravitational lensing for light emitted from the inner regions of accretion discs around black holes.
- There is a request for insights on how the accretion disc would appear to a distant observer.
- Another participant suggests using Google Scholar and the Astrophysics Data System for finding relevant academic papers, emphasizing the importance of detailed sources over general searches.
- A link to a specific article about the Milky Way's black hole is shared as a potential resource.
- One participant expresses gratitude for the assistance provided in the discussion.
Areas of Agreement / Disagreement
Participants generally agree on the need for detailed academic resources and the relevance of gravitational lensing in the context of black holes, but there is no consensus on specific models or interpretations of the observations discussed.
Contextual Notes
The discussion lacks specific mathematical formulations or detailed descriptions of the lensing effects, and the assumptions regarding the properties of the accretion discs are not fully explored.
