AGNs with hard $\gamma$-ray emission identified so far are radio-loud. III Zw2 is a radio intermediate AGN with a relativistic jet. We study its spectralenergy distribution (SED) and find that the broad band emissions are dominatedby the non-thermal emissions from the jet. We model its SED through asynchrotron + inverse Compton (IC) model. The results show that the ICcomponent of III Zw 2 peaks at a few MeV, and the flux density drops rapidly athigher energy with photon index $\Gamma\approx3.3$ above 0.1 GeV. The predictedflux is slightly over the sensitivity of $Fermi$/LAT, but it is not included inthe first $Fermi$/LAT AGN catalog. The reason for this may be: 1) that the ICpeak is low and the spectrum is very steep above 0.1 GeV, 2) that III Zw 2 isin the low state during the period of the $Fermi$/LAT operation. We also findthat III Zw 2 follows similar jet processes as those in $\gamma$-ray AGNs,e.g., the relation between jet power and radiation power, called the blazarsequence. We suggest that III Zw 2 may be a young source at an earlier stage ofjet activity.

Possible gamma-ray emission of radio intermediate AGN III Zw 2 and its implication on the evolution of jets in AGNs
