X-RAY ABSORPTION IN QUASAR HOST GALAXIES
ABSTRACT
Recent HST observation of quasar host galaxies revealed variety of host galaxy type of quasars. We pick up two quasars PG0052+251(z=0.155) and PG1012+008(z=0.185) from 20 quasars studied by Bahcall et al., of which host were found to be a (edge on) spiral and an interacting galaxy with HST. We expect to detect significant absorption due to the quasar host galaxies with ASCA observation. ASCA observation of distant quasars revealed significant absorption is found in the X-ray spectra. Though its origin has not yet been clear, our observation will provide estimate of the absorption due to host galaxy with this proposal.
