Abstract (from CDS):

We report the discovery of up to 35 new supernova remnants (SNRs) from a 42" resolution, 90 cm multiconfiguration Very Large Array survey of the Galactic plane covering 4°.5<l<22°.0 and {mid}b{mid}<1°.25. Archival 20 cm, 11 cm, and 8 µm data have also been used to identify the SNRs and constrain their properties. The 90 cm image is sensitive to SNRs with diameters 2'.5 to 50' and down to a surface brightness limit of ∼10–21 W/m2/Hz/sr. This survey has nearly tripled the number of SNRs known in this part of the Galaxy and represents an overall 15% increase in the total number of Galactic SNRs. These results suggest that further deep, low-frequency surveys of the inner Galaxy will resolve the discrepancy between the expected number of Galactic SNRs and the significantly smaller number of currently known SNRs.
