This is happening in binary systems. The black hole is not emitting any detectable X-rays from objects falling into it. There are none falling into it then. It is non interacting. But we know it is non interacting because it Doppler shifts a nearby object in the binary systems these scientists are observing. Being a binary system, unless the objects are at beyond perfect equilibrium with respect to their accelerations, the objects will eventually collide (in a true binary system). In other words, the Doppler shifting object must be actually falling, however slowly, into the black hole. My question is this: Can we assume that the object is heating up and emiting additional x rays
