IRAS 09104+4109

[11][12] IRAS 09104+4109 has a luminosity bolometer of ~ 1012.6 h−2 Lsun, which its optical spectrum is characterized by presence of narrow emission lines.

[16] Further studies in 2012, showed that IRAS 09104+4109 is a rare example of a dust enshrouded quasar, associated with a double-lobed radio source at the position angle of =333°.

[17] However, the steep radio spectral index and misalignment between the jets and ionized optical emission suggested that the orientation of the quasar in IRAS 09104+4109 had changed.

[13] This results suggested that the realignment of the quasar, the cessation of jet activity and the onset of rapid star formation in IRAS 09104+4109, may have been caused by a gas-rich galaxy merger.

This gas is comparable to the scale of the filamentary nebula in the Perseus cluster, falling within the thermal instability radius of the intracluster medium (ICM), within ~70 kpc.

These observations suggest that the ICM cooling is not strongly affected by its buried quasar which can build gas reservoirs to fuel reorientation and quasar-activity of its central AGN.
