I seriously doubt this is any surprise to
experienced astronomers as it has been known for some time that ejection of Quasars from Seyfert-type Galaxies "scintillate" at various radio frequencies.
It is further thought a "jet" resulting from this occurrence must be directed almost in our direction and boosted to a velocity extremely close to the velocity of light. Of course boosting to this velocity requires an enormous amount of energy.
