Cassiopeia A: dust factory revealed via submillimetre polarimetry
L. Dunne, S. J. Maddox, R. J. Ivison +7
If Type-II supernovae - the evolutionary end points of short-lived, massive stars - produce a significant quantity of dust (>0.1 M_sun) then they can explain the rest-frame far-inf…
Cas A: The Bright X-ray Knots and Oxygen Emission
D. Dewey, T. DeLaney, J. S. Lazendic
Chandra High-Energy Transmission Grating (HETG) X-ray spectra are extracted from 17 bright, narrow regions of Cas A and provide unique measurements of their kinematic and plasma st…
Spitzer IRAC Images and Sample Spectra of Cassiopeia A's Explosion
J. A. Ennis, L. Rudnick, W. T. Reach +5
We present Spitzer IRAC images, along with representative 5.27 to 38.5 micron IRS spectra of the Cassiopeia A supernova remnant. We find that various IRAC channels are each most se…
Canonical Particle Acceleration in FRI Radio Galaxies
Andrew Young, Lawrence Rudnick, Debora Katz +3
Matched resolution multi-frequency VLA observations of four radio galaxies are used to derive the asymptotic low energy slope of the relativistic electron distribution. Where avail…
A Million-Second Chandra View of Cassiopeia A
Una Hwang, J. Martin Laming, Carles Badenes +20
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW count…
Kinematics of X-ray Emitting Components in Cassiopeia A
T. DeLaney, L. Rudnick, R. Fesen +3
We present high-resolution X-ray proper motion measurements of Cassiopeia A using Chandra observations from 2000 and 2002. We separate the emission into four spectrally distinct cl…
