We present the results of timing analysis of XMM-Newton observations of Seyfert 2 galaxies in order to search for differences in the mean properties of Seyfert 1 galaxies and Seyfert 2 galaxies. We selected 13 Seyfert 2 galaxies from the XMM-Newton a

We are studying on a press forming of a 0.3-mm-thick foil in order to make advanced thin-foil substrates with a two-stage reflector for large X-ray telescopes. We press-formed one sheet of aluminum foil using a stamping die with high accuracy, and th

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
