{"Image DocumentName": "Blazars", "Image ImageDescription": "A Blazar is a very compact and highly variable energy source associated with a presumed supermassive black hole at the center of a host galaxy. Blazars are among the most violent phenomena in the universe. Blazars are active galactic nuclei (AGN) with a relativistic jet that is pointing in the general direction of the Earth. We observe down the jet, or nearly so, and this accounts for the rapid variability and compact features.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
