Fe-K Line Time variability and Ni abundance of Distant Reflector in Seyfert Galaxies

Yasushi Fukazawa, Shun'ya Furui, Kazuma Hayashi +3

We have performed systematic studies of narrow Fe-K line (6.4 keV) flux variability and Ni-K line intensity for Seyfert galaxies, using {\em Suzaku} and {\em XMM-Newton} archival d…
