About this work
This animation shows the events that serve as the basis of an astrophysics technique called "echo mapping," also known as reverberation mapping. At center is a supermassive black hole surrounded by a disk of material called an accretion disk. As the disk gets brighter it sometimes even releases short flares of visible light.
