The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
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…
Anatomy of the AGN in NGC 5548: II. The Spatial, Temporal and Physical Nature of the Outflow from HST/COS Observations
N. Arav, C. Chamberlain, G. A. Kriss +30
(Abridged) Our deep multiwavelength campaign on NGC 5548 revealed an unusually strong X-ray obscuration. The resulting dramatic decrease in incident ionizing flux allowed us to con…
A fast and long-lived outflow from the supermassive black hole in NGC 5548
J. S. Kaastra, G. A. Kriss, M. Cappi +31
Supermassive black holes in the nuclei of active galaxies expel large amounts of matter through powerful winds of ionized gas. The archetypal active galaxy NGC 5548 has been studie…
