We present far-ultraviolet (FUV) spectral imaging observations of the Vela supernova remnant (SNR) obtained with the SPEAR/FIMS instrument. The Vela SNR extends ~8° in the FUV, and its global spectra are dominated by shock-induced emission lines. We find that the global FUV line luminosities can exceed the 0.1-2.5 keV soft X-ray luminosity by an order of magnitude. The global O VI : C III ratio shows that the Vela SNR has a relatively large fraction of slower shocks compared with the Cygnus…

We present the general properties of the far-ultraviolet (FUV; 1370–1710 Å) continuum background over most of the sky, obtained with the Spectroscopy of Plasma Evolution from Astrophysical Radiation
Far-Ultraviolet Observations of the Ophiuchus Region with SPEAR
We present the first far-ultraviolet (FUV; 1370-1670 Å) image of the Ophiuchus molecular cloud region, observed with the SPEAR imaging spectrograph. The flux levels of the diffuse FUV continuum are
[Ne V] Imaging of N49 in the Large Magellanic Cloud
We present subarcsecond imaging in [Ne V] of N49, the brightest optical SNR in the LMC. Between the "cool" optical and "hot" X-ray regimes, [Ne V] emission indicates intermediate temperatures for

C iv EMISSION-LINE DETECTION OF THE SUPERNOVA REMNANT RCW 114
We report the detection of the C iv λλ1548,1551 emission line in the region of the RCW 114 nebula using the FIMS/SPEAR data. The observed C iv line intensity indicates that RCW 114 is much closer to
