Chemical evolution of the Universe at 0.7 < z < 1.6 derived from abundance diagnostics of the broad-line region of quasars
Hiroaki Sameshima, Yuzuru Yoshii, Kimiaki Kawara
We present an analysis of Mg II and Fe II UV emission lines for archival Sloan Digital Sky Survey (SDSS) quasars to explore diagnostics of the magnesium-to-iron abund…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
ASTRO-H White Paper - Chemical Evolution in High-z Universe
M. S. Tashiro, D. Yonetoku, M. Ohno +7
In this paper, we demonstrate ASTRO-H's capability to measure the chemical evolution in the high-z (z <~ 3) universe by observing X-ray afterglows of gamma-ray bursts (GRBs) and di…
ASTRO-H White Paper - AGN Winds
J. S. Kaastra, Y. Terashima, T. Kallman +23
In this white paper we describe the prospects for ASTRO-H for the study of outflows from active galactic nuclei. The most important breakthroughs in this field are expected to aris…
Supernova dust for the extinction law in a young infrared galaxy at z = 1
K. Kawara, H. Hirashita, T. Nozawa +6
We apply the supernova(SN) extinction curves to reproduce the observed properties of SST J1604+4304 which is a young infrared (IR) galaxy at z = 1. The SN extinction curves used in…
