The Unprecedented Discovery of a Spectral Blazar OJ 287
A new study has discovered a remarkable and unique source of gamma rays in the night sky. Scientists have found a blazar, or an active galactic nucleus called OJ 287, emitting intense gamma ray flares at unprecedented levels. The research team, led by the University of Turku in Finland, used the Fermi Large Area Telescope to observe the blazar’s spectral emission and found that the gamma rays are reaching energies of over 100 gigaelectronvolts. This makes OJ 287 the most energetic blazar ever observed in gamma rays. The study, which was recently published in The Astrophysical Journal, provides insight into the structure and properties of this extraordinary source.
