QSO B0153+744

[6] However, when shown at both frequencies, it is revealed as double source that is embedded inside a halo.

[7] In its radio structure, the 15.4 GHz emission is found to be dominated by two main components with a separation gap of 10 milliarcseconds.

[2] A strong one-sided jet is present in QSO B0153+744 with its projected direction changing by an 180° angle.

The two sub-components are shown trailing the jet's direction with a switch of 65° ± 3° at distance r = (0.65 ± 0.05) mas to 88° ± 8° at distance r = (1.35 ± 0.05) mas, while the third sub-component is trailing the jet's outermost regions.

[5] Based on the jet's speed and its change of direction, this indicates the radio source of QSO B0153+744 is relatively young.
