Images of gamma-ray flare from supermassive black hole M87
The jet is tens of millions of times larger than the black hole’s event horizon.
An international research team including UCLA has observed a teraelectronvolt gamma-ray flare seven orders of magnitude — tens of millions of times — larger than the event horizon, or surface of the black hole itself. A flare of this intensity — which has not been observed in over a decade — can offer crucial insights into how particles, such as electrons and positrons, are accelerated in the extreme environments near black holes. Jin contributed to analysis of the highest energy part of the dataset, called the very-high-energy gamma rays, which was collected by VERITAS — a ground-based gamma-ray instrument operating at the Fred Lawrence Whipple Observatory in southern Arizona.
