We discuss the X-ray , optical and radio properties of AX J0843+2942 , a high luminosity Type 2 AGN found in the ASCA Hard Serendipitous Survey .
The X-ray spectrum is best described by an absorbed power-law model with photon index of \Gamma = 1.72 ^ { +0.3 } _ { -0.6 } and intrinsic absorbing column density of N _ { H } = 1.44 ^ { +0.33 } _ { -0.52 } \times 10 ^ { 23 } cm ^ { -2 } .
The intrinsic luminosity in the 0.5 – 10 keV energy band is \simeq 3 \times 10 ^ { 45 } ergs s ^ { -1 } , well within the range of quasar luminosities .
AX J0843+2942 , positionally coincident with the core of a triple and strong ( S _ { 1.4 GHz } \sim 1 Jy ; P _ { 1.4 GHz } \sim 9 \times 10 ^ { 33 } erg s ^ { -1 } Hz ^ { -1 } ) radio source , is spectroscopically identified with a Narrow Line object ( intrinsic FWHM of all the permitted emission lines \mathrel { < \kern - 10.0 pt \lower 3.87 pt \hbox { $ \sim$ } } 1200 km s ^ { -1 } ) at z=0.398 , having line features and ratios typical of Seyfert-2 like objects .
The high X-ray luminosity , coupled with the high intrinsic absorption , the optical spectral properties and the radio power , allow us to propose AX J0843+2942 as a Radio-Loud “ Type 2 QSO ” .
A discussion of the SED of this object is presented here together with a comparison with the SED of Ultra Luminous Infrared Galaxies , other “ Type 2 QSO ” candidates from the literature , and “ normal ” Radio-Quiet and Radio-Loud QSOs .
