摘要: We present the C III ?977, O VI ??1032, 1038 and N IV] ?1486 emission line maps of Cygnus Loop, obtained with newly processed data Spectroscopy Plasma Evolution from Astrophysical Radiation (SPEAR; also known as FIMS) mission. In addition, Si IV+O complexes around 1400 ? are resolved into two separate lines whose intensity demonstrates a relatively high IV region that was predicted in previous study. The morphological similarity between X-ray images, well comparison value expected results, indicates large portions observed emissions could be produced emitting gas. Comparisons far-ultraviolet (FUV) images optical H I?21?cm reveal spatial variations shock-velocity populations FUV extinction direction previously identified I cloud. By calculating ratios for several subregions we investigate variation population radiative shock velocities effects resonance scattering, gas, nonradiative shocks. luminosity comparisons Loop Vela supernova remnant suggest fraction shocks early evolutionary stages is much larger Loop.
