A Pulsar Wind Nebula in the Oxygen-Rich Supernova Remnant G292.0+1.8

John P. Hughes, Patrick O. Slane, David N. Burrows +2

Using the Chandra X-ray Observatory we have discovered a diffuse, center-filled region of hard X-ray emission within the young, oxygen-rich supernova remnant (SNR) G292.0+1.8. Near…

A Broadband X-Ray Study of the Supernova Remnant 3C 397

S. Safi-Harb, R. Petre, K. A. Arnaud +5

We present an X-ray study of the radio bright supernova remnant (SNR) 3C 397 with ROSAT, ASCA, and RXTE. A central X-ray spot seen with the ROSAT High-Resolution Imager hints at th…

Evidence of X-ray Synchrotron Emission from Electrons Accelerated to 40 TeV in the Supernova Remnant Cassiopeia A

G. E. Allen, J. W. Keohane, E. V. Gotthelf +9

We present the 2-60 keV spectrum of the supernova remnant Cassiopeia A measured using the Proportional Counter Array and the High Energy X-ray Timing Experiment on the Rossi X-ray…

A Possible Site of Cosmic Ray Acceleration in the Supernova Remnant IC 443

Jonathan W. Keohane, R. Petre, E. V. Gotthelf +2

We present evidence for shock acceleration of cosmic rays to high energies (about 10 TeV) in the supernova remnant IC 443. X-ray imaging spectroscopy with ASCA reveals two regions…

A Comparison of X-ray and Radio Emission from the Supernova Remnant Cassiopeia A

Jonathan W. Keohane, Lawrence Rudnick, Martha C. Anderson

We compare the radio and soft X-ray brightness as a function of position within the young supernova remnant Cassiopeia A. A moderately strong correlation (r = 0.7) was found betwee…
