NASA’s Fermi Mission Creates 14-Year Time-Lapse of the Gamma-Ray Sky [1]
[]
Date: 2023-12
Somehow, the black holes produce extremely fast-moving jets of matter, and with blazars we’re looking almost directly down one of these jets, a view that enhances their brightness and variability. “The variations tell us that something about these jets has changed,” Racusin said. “We routinely watch these sources and alert other telescopes, in space and on the ground, when something interesting is going on. We have to be quick to catch these flares before they fade away, and the more observations we can collect, the better we’ll be able to understand these events.”
