PKS 1402+044 is aquasar located in the constellation ofVirgo. It has aredshift of 3.207, estimating the object to be located 11.3 billionlight-years away fromEarth.[1][2]

Characteristics

[edit]

PKS 1402+044 is classified as a broadabsorption-line quasar (BAL QSO) observed bySloan Digital Sky Survey[3] with a flat-spectrumradio source.[4][5] It is also classified ablazar, a type ofactive galaxy[6][7] and such produces a powerfulastrophysical jet that is shot out into the depths ofintergalactic space.[8]

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

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