Title: A systematic analysis of the physical parameters of Galactic SNRs
Abstract:

We present a meta-analysis of the physical parameters of Galactic Supernova Remnants based on a systematic literature review. We use data for 64 SNRs with published information (mainly from optical observations) regarding their shock or expansion velocity, density and temperature, based on a variety of methods and tracers. We also have further information on individual regions of 34 objects, providing a picture of the variation of the physical parameters within an object. We quantify this variation and we also discuss the effect of the different tracers on the diversity of the estimated values. We explore the correlations between the physical parameters of SNRs (such as velocity, density and excitation parameters) as a function of their age and type, providing for the first time a picture of the overall trends of the properties of the SNR population within our Galaxy. Comparison of the derived correlations with SNR evolution models shows very good agreement.
