Astronomers measure and model a blazing gamma-ray source

6 June 2016 Astronomy Now

A blazar is a galaxy whose central supermassive black hole emits a powerful jet of high velocity particles aimed almost directly at Earth. Astronomers have measured and successfully modelled the very high energy gamma ray emission from a blazar known as 1ES 1741+196 using VERITAS, the Very Energetic Radiation Imaging Telescope Array System.
