Thermal X-ray composites as an effect of projection
A new possibility is proposed to explain the nature of thermal X-ray composites (TXCs), i.e. a class of supernova remnants (SNRs) with a thermal X-ray centrally-filled morphology within a radio shell, as a projection effect of the 2- or 3-dimensional shell-like SNR evolv ed in a nonuniform medium with scale-height …
