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. WebThis happens because a ray pointing right above the black hole is bent down to meet the upper surface of the disk behind the hole, opposite the observer. ... This technique has the …
