Supermassive black hole corona,artwork
Supermassive black hole. Illustration showing a supermassive black hole corona shift. The black hole (lower frame in eech image) is surrounded by a swirling disk of material falling onto it,known as an accretion disk. The purplish ball of light represents a feature called the corona. This is not visible to the human eye,but contains highly energetic particles that generate X-rays. The corona may shift its position. It gathers inward (left),becoming brighter,before shooting away from the black hole (centre and right). When it moves closer to the black hole,it creates a flare of X-rays before shooting away again. X-ray flares are also produced when the corona travels toward us at very fast speeds. An effect called relativistic boosting normally occurs before a corona shift,intensifying X-rays reflected off material on one side of the accretion disk (which is travelling near half the speed of light),and dimming them the other side.
