“…They also noticed strong [O iii ] emission in 5007 Å. We note that our SHS Hα imaging is superior to Boumis et al (2008) with a clear Hα shell being evident with a particular concentration to the eastern side. The clear optical SNR counterpart is confirmed.…”

During detailed searches for new Galactic supernova remnants (SNRs) in the Anglo‐Australian Observatory/United Kingdom Schmidt Telescope (AAO/UKST) Hα survey of the southern Galactic plane, we also uncovered, for the first time, possible associated Hα emission in the vicinity of about 24 known Galactic SNRs previously known solely from radio or X‐ray observations. The possible optical counterparts to these known SNR were detected due to the 1‐arcsec resolution and 5 Rayleigh sensitivity of this Hα survey. The newly discovered emission frequently exhibits the typical filamentary form of other optically detected SNRs although sometimes the Hα emission clouds or fragmented filaments largely inside an SNR extend over the radio border. It is true that superposition of general diffuse and extended Galactic emission in the region of these remnants is a complicating factor, but for many optical candidates the Hα emission provides an excellent morphological and positional match to the observed radio emission so that an association seems clear. We have already published Hα images and confirmatory spectral observations for several of the best optical counterparts to known SNRs but for completeness and convenience we include them in our complete catalogue of previously known radio detected SNRs for which we have now uncovered Hα optical emission. For better visualization of the optical emissions from these faint supernova remnants and to enhance some low surface‐brightness features we also present quotient images of the Hα data divided by the accompanying broad‐band short‐red data. Out of 274 Galactic SNRs currently catalogued and detected in the radio only ∼20 per cent had previous optical counterparts. We may have now increased this by a further third by adding a further 24 candidate optical counterparts.

“…Therefore, we predict its distance is around 3 kpc. Boumis et al (2008) suggested a lower limit distance of 2.2 kpc for G15.1-1.6. The RC method gives an upper limit distance of 2.1 kpc.…”

We carry out a project to independently measure the distances of supernova remnants (SNRs) in the first quadrant of the Galaxy. In this project, red clump (RC) stars are used as standard candles and extinction probes to build the optical extinction (A V ) -distance(D) relation in each direction of extinction-known SNRs. The distances of 15 SNRs are well determined. Among them, the distances of G65.8-0.5, G66.0-0.0 and G67.6+0.9 are given for the first time. We also obtain 32 upper/lower limits of distances, and the distances to G5.7-0.1, G15.1-1.6, G28.8+1.5 and G78.2+2.1 are constrained. Most of the distances measured by the RC method are consistent with previous results. The RC method provides an independent access to the distances of SNRs.

“…We obtained a spectral index of α = −0.01±0.09, which is that of a thermal source. However, Boumis et al (2008) analysed optical observations and convincingly showed that G15.1−1.6 is a SNR. -G17.4−2.3.…”

Aims. We study the spectral and polarization properties of supernova remnants (SNRs) using our λ6 cm survey data. Methods. We analyse data from observations taken as part of the Sino-German λ6 cm polarization survey of the Galactic plane. By using the integrated flux densities at λ6 cm together with measurements at other wavelengths from the literature, we derive the global spectra of 50 SNRs. In addition, from the observations at λ6 cm we obtain the polarization images of 24 SNRs. Results. We derive integrated flux densities at λ6 cm for 51 small SNRs with angular sizes smaller than 1 • . We are able to derive global radio spectral indices in all the cases except for Cas A. For the SNRs G15.1−1.6, G16.2−2.7, G16.4−0.5, G17.4−2.3, G17.8−2.6, G20.4+0.1, G36.6+2.6, G43.9+1.6, G53.6−2.2, G55.7+3.4, G59.8+1.2, G68.6−1.2, and G113.0+0.2, the spectra have been significantly improved. From our analysis, we argue that the object G16.8−1.1 is probably an H ii region instead of a SNR. Cas A shows a secular decrease in total intensity, and we measure a flux density of 688 ± 35 Jy at λ6 cm between 2004 and 2008. We detect polarized emission from 25 SNRs. For G16.2−2.7, G69.7+1.0, G84.2−0.8, and G85.9−0.6, the polarized emission is detected for the first time confirming that they are SNRs. Conclusions. High-frequency observations of SNRs are difficult but essential to determine their spectra and measure their polarization in particular towards the inner Galaxy, where Faraday effects are important.
