OBSCURING TORI IN RADIO GALAXIES
ABSTRACT
Obscuration of central region of AGN by molecular torus is the essence of 'unified model' for radio-quiet AGNs. For radio-quiets, there is a good correlation between column densities (NH) derived from X-ray spectra and optical/NIR emission line width: small/large NH corresponds to type 1/2 objects. However, it is not yet clear whether the correlation is also seen in radio-loud AGNs. Although small/large NH are expected for broad/narrow line radio galaxies (BLRG/NLRG), under a simple extension of the 'unified scheme' from radio-quiet AGNs to radio-loud AGNs, some exceptions can be found in radio-loud AGNs. Therefore, we propose the observations of NLRG to test 'unified scheme for radio-loud AGNs' by examining whether all NLRG have large NH value.
