In this paper, we present new empirical radio surface-brightness-to-diameter (Σ–D) relations
for supernova remnants (SNRs) in our Galaxy. We also present new theoretical derivations …

We present updated empirical radio surface-brightness-to-diameter ($\Sigma-D $) relation
for supernova remnants (SNRs) in our Galaxy. Our original calibration sample of Galactic …

This paper examines relations between the radio surface brightness Σ and the diameter D
(also known as relations) for a sample of extragalactic supernova remnants (SNRs) as …

In this paper we present the updated empirical radio surface-brightness-to-diameter
($\Sigma $--$ D $) relation for Galactic supernova remnants (SNRs) calibrated using $110 …

The radio surface brightness-to-diameter (Σ–D) relation for supernova remnants (SNRs) in
the starburst galaxy M82 is analyzed in a statistically more robust manner than in the …

Technological advances in radio telescopes and X-ray instruments over the last 20 years
have greatly increased the number of known supernova remnants (SNRs) and have led to a …

In this work, we have constructed a relation between the surface brightness (Σ) and diameter
(D) of Galactic C-and S-type supernova remnants (SNRs). In order to calibrate the Σ-D …

During the last couple of decades of work on the Σ–D (radio surface brightness to diameter)
relation for supernova remnants (SNRs), it has been generally accepted that no single Σ–D …

We discuss the L–D correlation (possible dependence of radio luminosity on linear
diameter) for supernova remnants (SNRs) in order to see whether the Σ–D relation actually …

The selection effects applicable to the identification of Galactic supernova remnants (SNRs)
at radio wavelengths are discussed. Low surface brightness remnants are missing, as are …
