BCDDM: Branch-Corrected Denoising Diffusion Model for Black Hole Image Generation
Ao liu, Zelin Zhang, Songbai Chen +2
The properties of black holes and accretion flows can be inferred by fitting Event Horizon Telescope (EHT) data to simulated images generated through general relativistic ray traci…
