J/A+A/435/437  Brightness and diameters for extragalactic SNRs (Urosevic+, 2005)

The Σ-D relation for supernova remnants in nearby galaxies. Urosevic D., Pannuti T.G., Duric N., Theodorou A. <Astron. Astrophys., 435, 437-447 (2005)> =2005A&A...435..437U
ADC_Keywords: Galaxies, radio ; Galaxies, nearby ; Supernova remnants Keywords: ISM: supernova remnants - methods: statistical - radio continuum: galaxies Abstract: This paper examines relations between the radio surface brightness Sigma and the diameter D (also known as Sigma-D relations) for a sample of extragalactic supernova remnants (SNRs) as constructed from a combination of published data and data from our own surveys. Our sample of extragalactic SNRs is the largest ever devised for the purpose of analyzing Sigma-D relations. File Summary:

Note (1): TNG 38.9+42.5 corrected into TNG 38.9+22.5 by CDS Note (2): Notes on S1.4GHz as follows: a = S20 has been extrapolated from the values listed for α and S36 by Filipovic et al. (1998, Cat. J/A+AS/130/421). D = The flux densities are from the paper by Dickel & Milne (1995AJ....109..200D). e = S20 has been extrapolated from the values listed for α and S18 by Tarchi et al. (2000A&A...358...95T). Note (3): We adopted published values for the spectral index alpha (Snu∝nu-alpha) of these sources; if no spectral index was given, a value of 0.5 was assumed. Note (4): Notes on alpha as follows: b = No spectral index data available; a value of α=0.5 is assumed. c = S20 has been extrapolated from the values listed for α by McDonald et al. (2002MNRAS.334..912M) and S3.6 by Huang et al. (1994ApJ...424..114H).
