Asymmetric Expansion of the Youngest Galactic Supernova Remnant G1.9+0.3
K. J. Borkowski, P. Gwynne, S. P. Reynolds +4
The youngest Galactic supernova remnant (SNR) G1.9+0.3, produced by a (probable) SN Ia that exploded CE, is strongly asymmetric at radio wavelengths, much brighter in t…
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…
Nonuniform Expansion of the Youngest Galactic Supernova Remnant G1.9+0.3
K. J. Borkowski, S. P. Reynolds, D. A. Green +4
We report measurements of X-ray expansion of the youngest Galactic supernova remnant, G1.9+0.3, using Chandra observations in 2007, 2009, and 2011. The measured rates strongly devi…
Electron Heating, Magnetic Field Amplification, and Cosmic Ray Precursor Length at Supernova Remnant Shocks
J. Martin Laming, Una Hwang, Parviz Ghavamian +1
We investigate the observability, by direct and indirect means, of a shock precursor arising from magnetic field amplification by cosmic rays. We estimate the depth of such a precu…
Interstellar and Ejecta Dust in the Cas A Supernova Remnant
Richard G. Arendt, Eli Dwek, Gladys Kober +2
Infrared continuum observations provide a means of investigating the physical composition of the dust in the ejecta and swept up medium of the Cas A supernova remnant. Using low re…
A High-Resolution X-Ray and Optical Study of SN 1006: Asymmetric Expansion and Small-Scale Structure in a Type Ia Supernova Remnant
P. Frank Winkler, Brian J. Williams, Stephen P. Reynolds Robert Petre +3
We introduce a deep (670 ks) X-ray survey of the SN1006 remnant from Chandra, plus a deep H-alpha image from the 4m telescope at CTIO. Comparison with Chandra images from 2003 give…
