4C+74.26 is a quasar located about 1.4 billion light years away from us - one of the few quasars with giant radio lobes spreading across millions light years. An team of researchers led by Dr. Gopal Bhatta from the Jagiellonian University in Kraków studied the source using multifrequency observations from the ground and space based telescopes. The team discovered that the optical emission delayed behind radio emission by ~250 days. The authors proposed that the delay may indicate a scenario in which flux modulations arose due to magnetic disruptions at the innermost regions of the accretion disk. Such a lag between two emission bands is relatively rarely observed and it could help in understating the most challenging issues in modern astrophysics. More...
