[8][1] Such BL Lac objects like PKS 1144-379 are rare active galactic nuclei class, characterized by all frequencies, and absence of emission lines.

[10] The quasar is dominated by its bright compact radio core, but according to maps that is made with a high dynamic range, it shows an extended structure.

PKS 1144-379 also has a luminosity above both FR I/FR II limit ~ 1032 erg s−1 Hz−1 at 5 GHz[11] and such also classfied as a blazar,[12][13] a type of active galaxy that is producing radiation, observed at wavelengths from radio to gamma rays.

[19] From the results studying the variability behavior of PKS 1144–379, researchers found the optical variation is 1.92 mag.

[21] The core component of PKS 1144-379 is found to be compacted, which its angular size varied between the ranges of 5.65-15.90 Чas estimating to be 0.05-0.13 pc.

[23] According to observations by Fermi, PKS 1144-379 has a column dissipation radius of 64.5 x 1015 cm (430) RS with an accretion disc luminosity of 1045 erg s−1 3 x (0.04) LEdd.
