The ASTRO-H Mission
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +174
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
High-resolution x-ray telescopes
S. L. O'Dell, R. J. Brissenden, W. N. Davis +21
High-energy astrophysics is a relatively young scientific field, made possible by space-borne telescopes. During the half-century history of x-ray astronomy, the sensitivity of foc…
Steady X-Ray Synchrotron Emission in the Northeastern Limb of SN 1006
Satoru Katsuda, Robert Petre, Koji Mori +4
We investigate time variations and detailed spatial structures of X-ray synchrotron emission in the northeastern limb of SN 1006, using two Chandra observations taken in 2000 and 2…
Radioactive Scandium in the Youngest Galactic Supernova Remnant G1.9+0.3
Kazimierz J. Borkowski, Stephen P. Reynolds, David A. Green +4
We report the discovery of thermal X-ray emission from the youngest Galactic supernova remnant G1.9+0.3, from a 237-ks Chandra observation. We detect strong K-shell lines of Si, S,…
Discovery of X-Ray-Emitting O-Ne-Mg-Rich Ejecta in the Galactic Supernova Remnant Puppis A
Satoru Katsuda, Una Hwang, Robert Petre +3
We report on the discovery of X-ray--emitting O-Ne-Mg-rich ejecta in the middle-aged Galactic O-rich supernova remnant Puppis A with Chandra and XMM-Newton. We use line ratios to i…
X-Ray Measured Dynamics of Tycho's Supernova Remnant
Satoru Katsuda, Robert Petre, John P. Hughes +5
We present X-ray proper-motion measurements of the forward shock and reverse-shocked ejecta in Tycho's supernova remnant, based on three sets of archival Chandra data taken in 2000…
