概要

• 論文の詳細を見る

• We found short time variability (Δt 〜 1 ks) of NGC 6300 in the 2-10 keV band with XMM-Newton. Its normalized power spectral density can be expressed by a power-law function of frequency with a slope of 〜-1.7. These results are similar to those of Seyfert 1 galaxies. Using the relation between time variability and central black hole mass, we estimate the black hole mass of about 3×10^5 M_<⊙>. The time variability analysis suggests that NGC 6300 actually has a Seyfert 1 nucleus obscured by a thick matter.
