Expanding Ejecta in the Oxygen-Rich Supernova Remnant G292.0+1.8: Direct Measurement through Proper Motions
P. Frank Winkler, Karl Twelker, Claudine N. Reith +1
We report here the first study of proper motions of fast filaments in the young, oxygen-rich supernova remnant G292.0+1.8, carried out using a series of [O III] 5007 A emission-lin…
Dust Destruction in Type Ia Supernova Remnants in the Large Magellanic Cloud
Kazimierz J. Borkowski, Brian J. Williams, Stephen P. Reynolds +9
We present first results from an extensive survey of Magellanic Clouds supernova remnants (SNRs) with the Spitzer Space Telescope. We describe IRAC and MIPS imaging observations at…
The SN 1006 Remnant: Optical Proper Motions, Deep Imaging, Distance, and Brightness at Maximum
P. Frank Winkler, Gaurav Gupta, Knox S. Long
We report the first measurement of proper motions in the SN1006 remnant (G327.6+14.6) based entirely on digital images. CCD images from three epochs spanning a period of 11 years a…
HST-STIS Observations of the Cygnus Loop: Spatial Structure of a Non-radiative Shock
Ravi Sankrit, W. P. Blair, J. C. Raymond +1
We present a spatially-resolved ultraviolet spectrum of a non-radiative shock front in the Cygnus Loop, obtained with the Space Telescope Imaging Spectrograph (STIS) on board the H…
The Distance to the Cygnus Loop from Hubble Space Telescope Imaging of the Primary Shock Front
William P. Blair, Ravi Sankrit, John C. Raymond +1
We present a Hubble Space Telescope/WFPC2 narrow-band H-alpha image of a region on the northeastern limb of the Cygnus Loop supernova remnant. This location provides a detailed exa…
