In оbservаtiоnаl аstrоnomy, information can be obtained with three different tools: , which describe the spatial distribution of photons, , which illustrate the temporal evolution of the source intensity, and , diagrams of intensity vs. frequency (or wavelength). In general, in black hole systems, the direct imaging of the (which emits mostly in the visible, UV and soft X-ray bands) is impossible because of its compactness: its subtended angle is too small for the angular resolution of current telescopes. However, one can often resolve the (when present), thanks to interferometric observations in the radio band.
