PKS 1148-001 also known as UM 458 and 4C -00.47, is a quasar located in the constellation of Virgo. Its redshift is 1.979, estimating the object to be located 10.2 billion light-years from Earth.[1]
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]
