Using interplanetary scintillations and very-long-baseline interferometry it was determined that the radio source associated with the quasar has an apparent size of 0.1 arcseconds.[2] An one-sided jet has been observed in the milliarcsecond scale. The most accepted theory for the creation of radio jets is the presence of a supermassive black hole which accretes material.[3]
