Scientific paper

We studied host galaxies of 15 hard X-ray selected type 2 AGNs (median redshift is 0.22). Thanks to the intrinsic obscuration of a bright nucleus, we can decompose galaxies and derive spheroid luminosities. We can also derive a black hole masses in the sample AGNs from the absorption corrected X-ray luminosity assuming an Eddington ratio. The resultant black hole mass to spheroid luminosity relation at the redshifts does not show a significant evolution from z ˜ 0.
