Dark Matter Annihilation

Dark matter particles could be their own antimatter partners. Therefore, annihilation could occur if two dark matter particles collide. These are two dark matter particles that we can't see at all, they don't interact with anything. Eventually two of them come in and hit each other here and they annihilate through some process that we don't know. And in the end there's e+ and e-, electrons and positrons. And these electrons and positrons, as soon as they're produced, they're in a magnetic field. And so they start spiraling around the magnetic field producing synchrotron as soon as that happens. And that synchrotron radiation is what we think we see in the haze.
