The distribution of radioactive Ti in Cassiopeia A
Brian W. Grefenstette, Chris L. Fryer, Fiona A. Harrison +28
The distribution of elements produced in the inner-most layers of a supernova explosion is a key diagnostic for studying the collapse of massive stars. Here we present the results…
Locating the most energetic electrons in Cassiopeia A
Brian W. Grefenstette, Stephen P. Reynolds, Fiona A. Harrison +17
We present deep (2.4 Ms) observations of the Cassiopeia A supernova remnant with {\it NuSTAR}, which operates in the 3--79 keV bandpass and is the first instrument capable of sp…
The Density and Mass of Unshocked Ejecta in Cassiopeia A through Low Frequency Radio Absorption
Tracey DeLaney, Namir E. Kassim, Lawrence Rudnick +1
Characterizing the ejecta in young supernova remnants is a requisite step towards a better understanding of stellar evolution. In Cassiopeia A the density and total mass remaining…
The Proper Motion of the Neutron Star in Cassiopeia A
Tracey DeLaney, Joseph Satterfield
Images from the High Resolution Camera on the Chandra X-ray Observatory were used to measure the proper motion of the neutron star in Cassiopeia A over a baseline of 10 years (1999…
Nucleosynthetic Layers in the Shocked Ejecta of Cassiopeia A
Karl Isensee, Greg Olmschenk, Lawrence Rudnick +6
We present a 3-dimensional analysis of the supernova remnant Cassiopeia A using high resolution spectra from the Spitzer Space Telescope. We observe supernova ejecta both immediate…
The Three-Dimensional Structure of Cassiopeia A
Tracey DeLaney, Lawrence Rudnick, M. D. Stage +9
We used the Spitzer Space Telescope's Infrared Spectrograph to map nearly the entire extent of Cassiopeia A between 5-40 micron. Using infrared and Chandra X-ray Doppler velocity m…
