A Near-Infrared and X-ray Study of W49B: A Wind Cavity Explosion
Jonathan W. Keohane, William T. Reach, Jeonghee Rho +1
We present near-infrared narrow-band images of the supernova remnant W49B, taken with the WIRC instrument on the Hale 200 inch telescope on Mt. Palomar. The 1.64 micron [Fe II] ima…
PROMPT: Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes
D. Reichart, M. Nysewander, J. Moran +11
Funded by $1.2M in grants and donations, we are now building PROMPT at CTIO. When completed in late 2005, PROMPT will consist of six 0.41-meter diameter Ritchey-Chretien telescopes…
An X-Ray Point Source and Synchrotron Nebula Candidate in the Supernova Remnant G292.0+1.8
Charles M. Olbert, Jonathan W. Keohane
We present archival data from the Chandra X-Ray Observatory that reveal a bright point source to the southeast of the center of the young supernova remnant G292.0+1.8 that is coinc…
A Bow Shock Nebula Around a Compact X-Ray Source in the Supernova Remnant IC443
C. M. Olbert, C. R. Clearfield, N. E. Williams +2
We present spectra and high resolution images of the hard X-ray feature along the southern edge of the supernova remnant IC443. Data from the Chandra X-ray Observatory reveal a com…
The X-ray Expansion of the Supernova Remnant Cassiopeia A
Barron Koralesky, L. Rudnick, E. V. Gotthelf +1
We present the first X-ray expansion measurement of the SNR Cas A. We compared new ROSAT to archived Einstein HRI images with a separation of 17 years. The remnant is seen to be ex…
Evidence for Proportionate Partition Between the Magnetic Field and Hot Gas in Turbulent Cassiopeia A
J. W. Keohane, E. V. Gotthelf, R. Petre
We present a deep X-ray observation of the young Galactic supernova remnant Cas A, acquired with the ROSAT High Resolution Imager. This high dynamic range (232 ks) image reveals lo…
