PKS 2004-447

[10][11] In October 2019, it was found to exhibit a gamma ray flare,[12] reaching a highest flux of (1.3 ± 0.2) x 10−6 photon cm−2 s−1 at gamma-ray energies (0.1-300 GeV).

There is a jet structure emerging from the core with a projected position angle measurement of -90°, which bends to -60° at 20 mas.

This jet structure is further divided into two subcomponents enveloped completely from sight by the diffused emission.

It has a bulge showing a relatively low Sersic index of n ~ 1.2 with a bulge-to-total ratio of (B/T = 0.39 ± 0.02) for its J-band and (B/T = 0.44 ± 0.03) for its Ks-band.

[15] The host galaxy shows two faint spiral arms[16] and has an estimated black hole mass of 9 x 107 Mʘ.
