PKS 1148−001
PKS 1148−001, also known as UM 458 and 4C−00.47, is a quasar in the Virgo constellation. It has a redshift of 1.979, placing it about 10.2 billion light-years away. The quasar appears very bright and compact in the sky, with its radio source spanning about 0.1 arcseconds. Very-long-baseline interferometry shows a one-sided jet emerging from its center on milliarcsecond scales. The most accepted explanation for these radio jets is a supermassive black hole at the core actively pulling in material. Coordinates: right ascension 11h 50m 43.871s, declination −00° 23′ 54.20″.
