So, just to figure all that, what is seen? What is seen in a black hole image is not the black hole itself, but a light that's emitted by ordinary electrons in the surrounding, increasing this behavior can be modeled. And if dark matter particles were annihilating near the black hole, they would produce extra electrons and positrons whose radiation looks a bit different than normal emission. And the distinction emerges in spatial distribution in the MAD model, which are electrons concentrated in the secretion disk, with small populations in the jet region, creating a dark shadow. But electrons and positrons from dark matter annihilation would be distributed more uniformly through a disc in the jet region, because dark matter annihilation continuously supplies particles, even where astrophysical processes produce few electrons.
