Radio AGN jet alignment: Radio and Optical Position Angle of Radio Galaxies

Understand

It is well established that AGNs play an important role in the evolution of galaxies.

• These AGNs can be linked to the accretion processes onto massive black holes and past merger events in their host galaxies, which may lead to different alignments of the jets with respect to the host galaxies.
• This paper presents a study of the PA differences between radio and optical images of radio AGNs based on the LoTSS DR2, the FIRST, the DESI Legacy Imaging Surveys and the SDSS.
• We assessed PA measurement biases in the data and classified the radio AGNs based on the radio luminosity and infrared colour from the WISE.
