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…
X-ray Spectral Model of Reprocessing by Smooth and Clumpy Molecular Tori in Active Galactic Nuclei with the MONACO framework
Shun'ya Furui, Yasushi Fukazawa, Hirokazu Odaka +3
We construct an X-ray spectral model of reprocessing by a torus in an active galactic nucleus (AGN) with a Monte Carlo simulation framework MONACO. Two torus geometries of smooth a…
An emergence of new polarized emission region in blazar Mrk 421 associated with X-ray flare
Ryosuke Itoh, Yasushi Fukazawa, Yasuyuki T. Tanaka +8
We report on long-term multi-wavelength monitoring of blazar Mrk~421 from 2010 to 2011. The source exhibited extreme X-ray flares in 2010. Our research group performed optical phot…
