WebImages from the vicinity of the black hole horizon at the Galactic centre (Sgr A*) could be obtained in the near future with a Very Large Baseline Array of sub-millimetre telescopes. … WebMay 3, 2024 · Black hole ray-tracing programs typically distribute rays on an evenly spaced grid (see, e.g., Gold et al. 2024). In this approach, regions of the image with sharp, bright features are sampled with the same density of rays as the faint regions of only diffuse structure. Black hole images are expected to have regions of both categories.
