A possible relation between spectral index and z-distribution for supernova remnants.
Abstract
A statistical relation has been found between spectral index and the mean distance from the galactic plane for supernova remnants. Using z-distances calculated from the Sigma-D relationship and the observed spectral indices at radio frequencies for 93 galactic supernova remnants, the mean z-distance is found to vary from 175 pc to 60 pc for remnants with flat and steep spectra, respectively. A possible correlation between flat-spectra supernova remnants and pulsars is discussed.
