Fryer,Parviz Ghavamian,John P. Hughes,Jon A. Morse,Paul P. Plucinsky,Robert Petre,Martin Pohl,Lawrence Rudnick,Ravi Sankrit,Patrick Slane,Randall K. Smith,Randall K. Smith,Jacco Vink,Jessica S.

TL;DR: In this paper, Chandra X-ray images of the supernova remnant Cassiopeia A were used to study the bipolar structure of the Si-rich ejecta (NE jet and SW counterpart) and their chemical similarity is confirmed by their spectra.
Journal ArticleDOI
Freshly Formed Dust in the Cassiopeia A Supernova Remnant as Revealed by the Spitzer Space Telescope
Jeonghee Rho,Takashi Kozasa,William T. Reach,Lawrence Rudnick,Tracey DeLaney,J. D. T. Smith,J. Ennis,Haley Louise Gomez,A. Tappe +8 more
TL;DR: In this paper, the authors performed Spitzer Infrared Spectrograph mapping observations covering nearly the entire extent of the Cassiopeia A supernova remnant (SNR), producing mid-infrared (5.5-35 micron) spectra every 5-10".

Freshly formed dust in the cassiopeia a supernova remnant as revealed by the Spitzer space telescope
Jeonghee Rho,Takashi Kozasa,William T. Reach,J. D. T. Smith,Lawrence Rudnick,Tracey DeLaney,J. Ennis,Haley Louise Gomez,Achim Tappe,Achim Tappe +9 more
TL;DR: In this paper, the authors performed Spitzer Infrared Spectrograph mapping observations covering nearly the entire extent of the Cassiopeia A supernova remnant (SNR), producing mid-infrared (5.5-35 μm) spectra every 5"-10".
Journal ArticleDOI
The Three-dimensional Structure of Cassiopeia A
Tracey DeLaney,Lawrence Rudnick,M. D. Stage,J. D. T. Smith,Karl Isensee,Jeonghee Rho,Glenn E. Allen,Haley Louise Gomez,Takashi Kozasa,William T. Reach,John E. Davis,J. C. Houck +11 more
TL;DR: The authors used the Spitzer Space Telescope's Infrared Spectrograph to map nearly the entire extent of Casiopeia A between 5 and 40 μm, using infrared and Chandra X-ray Doppler velocity measurements.
Journal ArticleDOI
Cavity of molecular gas associated with supernova remnant 3c 397
Bing Jiang,Yang Chen,Yang Chen,Junzhi Wang,Junzhi Wang,Yang Su,Xin Zhou,Samar Safi-Harb,Tracey DeLaney +8 more
TL;DR: In this article, a (12)CO line broadening of the similar to 32 km s(-1) component is detected at the westmost boundary of the remnant, which provides direct evidence of the SNR MC interaction and suggests multi-component gas there with dense (similar to 10(4) cm(-3)) molecular clumps.
