[2][3][4] Detected from high-resolution 12-mm and 3-cm images, obtained by the Australia Telescope Compact Array, the galaxy is found to have a Type-II active galactic nucleus (AGN) showing two radio lobes.
With a rest-frame of -9600 rad m-2, the eastern radio lobe holds a record for the highest Faraday rotation measure to date, signifying a strong magnetic field or either a dense circumgalactic medium.
[11] Apart from that, the galaxy is found to exhibit both hot dust emission at 8.0 μm, with a significant internal visual extinction (~1.6 mag), inferred from Spitzer Space Telescope near/mid-IR imaging.
[5] According to researchers who observed PKS 0529-549 from Atacama Large Millimeter Array in Chile, it contains chlorine [C I] and doubly ionized oxygen [O III] which display regular velocity gradients.
Not to mention, it hosts a powerful radio-loud active galactic nucleus, with large amount of energy injected into its interstellar medium.
Local galaxies that have similar masses as PKS 0529-549 normally have rotation curves, peaking at very small radii (R ≲ 1 kpc).
