And the gravitational pull of a supermassive black hole causes dark matter to concentrate in the vicinity forming a dark matter spike. And these regions achieve densities, orders of magnitude higher than anywhere else in the galaxy. And since dark matter annihilation rates depend on density squared, these enhanced densities could produce detectable signals if the annihilation occurs at all. We're still not sure of that. So the research team developed a framework that builds directly on the MAD model by adding dark matter physics to the astrophysical baseline. So the team applied a general well-probistic magnetohydrodynamic simulation along with detailed particle propagation modeling. And they could then model how electrons and positrons from hypothetical dark matter annihilation would behave in a magnetic field structure as extracted from the MAD model positrons to stop it.
