PKS 1402 044 is a quasar located in the constellation of Virgo. It has a redshift of 3.207, estimating the object to be located 11.3 billion light-years away from Earth.[1][2]

Characteristics

[edit]

PKS 1402 044 is classified as a broad absorption-line quasar (BAL QSO) observed by Sloan Digital Sky Survey[3] with a flat-spectrum radio source.[4][5] It is also classified a blazar, a type of active galaxy[6][7] and such produces a powerful astrophysical jet that is shot out into the depths of intergalactic space.[8]

The blazar is known to be in its quiescent state, but it shows repeated periods of outbursts that are visible throughout the electromagnetic spectrum.[9] According to observations from Gamma-Ray Blazar Survey and Fermi Gamma-Ray Space Telescope, PKS 1402 044 is found optically variable with >6σ significance,[10] γ-ray detected and more Compton dominated than high synchrotron peaked (HSP) BL Lac objects.[11]

Through radio imaging by researchers, the quasar is core-dominated with fluctuating radio emission and radio morphology found smaller in comparison of steep-spectrum quasars.[12] The quasar is radio-loud with straightened jet magnetic fields along its source axis and a lobe field found to have a misaligned orientation.[13]
