We present a detailed structural study of the hot ISM in Galactic halo along sight line toward bright active galactic nucleus Mkn 421. The O VII and VIII absorption lines were measured with Low Energy Transmission Grating Spectrograph aboard Chandra 421, emission observed vicinities X-ray Imaging Spectrometer Suzaku. jointly analyzed spectra assuming exponential distributions gas temperature density from plane, constrained at plane to be 2.7(+0.6,-0.5)×106 K 1.5(+0.7,-0.5)×10−3 cm−3, scale...
A superconducting phase-transition microcalorimeter is a promising detector for high resolution X-ray spectroscopy. We are developing such future Japanese astronomy missions. In our design, tin absorber electrodeposited as mushroom structure to achieve covering fraction. have succeeded in detecting X-rays with the first model of calorimeter an absorber, though energy was limited due residual resist. also low transition temperature. describe results these experiments, and discuss limiting...
This white paper addresses selected new (to X-ray astronomy) physics and data analysis issues that will impact ASTRO-H SWG observations as a result of its high-spectral-resolution microcalorimeter, the focussing hard optics corresponding detectors, low background soft gamma-ray detector. We concentrate on atomic nuclear physics, including basic bound-bound bound-free transitions well scattering radiative transfer. The major topic categories include charge exchange, solar system sources,...
