Exploring the Damped Lyman-alpha Clouds with AXAF
Abstract
The High Energy Transmission Grating (HETG) Spectrometer on the Advanced X-ray Astrophysics Facility (AXAF) (scheduled for launch in August, 1998) will provide a new tool for the study of absorption in the X-ray spectra of high redshift quasars due to the material along the line of sight. In this paper we try to explore the possibility of using AXAF HETG to detect resonance absorption lines from the Damped Lyman-alpha (DLA) clouds.
