Iron-Rich Ejecta in the Supernova Remnant DEM L71
John P. Hughes, Parviz Ghavamian, Cara E. Rakowski +1
Chandra X-ray observations of DEM L71, a supernova remnant (SNR) in the Large Magellanic Cloud (LMC), reveal a clear double shock morphology consisting of an outer blast wave shock…
Far Ultraviolet Spectra of a Non-Radiative Shock Wave in the Cygnus Loop
John Raymond, Parviz Ghavamian, Ravi Sankrit +2
Spatial and spectral profiles of O VI emission behind a shock wave on the northern edge of the Cygnus Loop were obtained with the FUSE satellite. The velocity width of the narrowes…
The Optical Spectrum of the SN 1006 Supernova Remnant Revisited
Parviz Ghavamian, P. Frank Winkler, John C. Raymond +1
We present the deepest optical spectrum acquired to date of Balmer-dominated shocks in the NW rim of SN 1006. We detect the broad and narrow components of H-alpha, H-beta and H-gam…
