PG 1634+706

Seyfert galaxy

The X-ray spectrum of the PG 1634+706 (z=1.084), as observed with the ASCA SIS detectors. Unlike lower-redshift Seyfert 1 galaxies, this quasar shows no evidence for iron K-alpha fluorescence. This may be related to the high luminosity of the source, which might indicate a high accretion rate, and therefore an ionized accretion disk.
