[37.07] The X-ray view of the nuclei of FRII radio galaxies

M. Gliozzi, A. Rinn (GMU), R. Sambruna (NASA GSFC)

Fanaroff Riley II radio galaxies (FRIIs) can be divided into three subclasses based on their optical spectral properties: 1) objects with broad emission lines (BLO); 2) objects with high ionization narrow lines, which are considered obscured versions of BLO; 3) objects with low ionization narrow lines, whose optical properties are very similar to FRIs. We use the available data from the Chandra and XMM-Newton archives to investigate the nuclear properties of FRIIs. We show that the X-ray spectroscopy is able to discriminate between the three subclasses, and provides important clues on the physical conditions at the core of FRIIs.
