Spectacular outburst lets scientists peer into quasars
An outburst from a distant quasar known as PKS 1441+25 in April of this year gave astronomers at the gamma-ray telescope VERITAS an opportunity to measure the density of the optical “fog” that lies between the quasar and Earth and to deduce the surprising separation of the high-energy emission from the black hole that drives it.
Astrophysicists spot pulsed radiation from Crab Nebula that wasn’t supposed to be there
The VERITAS array of telescopes has detected pulsed gamma rays from the pulsar at the heart of the Crab Nebula that have energies far higher than the common theoretical models can explain. The finding is one of the most exciting in the telescope’s history, according to consortium members at Washington University in St. Louis.
Washington University physicists are closing in on the origin of cosmic rays
Nearly 100 years after the discovery of cosmic rays, a new type of gamma-ray telescope is finally allowing physicists to make images of cosmic-ray nurseries.
