We present an analysis of the first two XRISM/Resolve spectra of the well-known Seyfert-1.5 active galactic nucleus (AGN) in NGC 4151, obtained in 2023 December. Our work focuses on the nature of the narrow Fe K _α emission line at 6.4 keV, the stro

We measured the reflectivity of an Athena silicon pore optics sample coated with 10-nm thick iridium near the iridium L-edges (L3 , L2, and L1) in a step of 1.5 eV. The derived atomic scattering factor f2 was similar to a shape of the absorption coef

Methods for enhancing the gripping ability of microtweezers are examined in terms of friction force. Two aspects are investigated experimentally. One is a method for increasing the coefficient of friction of the handling part of the microtweezers. We
