Abstract

The Virginia Tech Spectral Line Survey (VTSS) Galactic Plane Hydrogen-Alpha Survey has the strong ability to search and discover many different types of objects that cannot be identified clearly on red plates and by other Multi-Wavelength Sky Surveys. Here we make a visual search from the VTSS fields with the supportive surveys of Southern Hydrogen-Alpha Sky Survey Atlas (SHASSA) and MDW Hydrogen-Alpha Sky Survey (MDWS) fields, in the Galactic latitude of |b| between -17 ° and 7 ° for several new optical emission nebulae. Seven candidates were chosen as most likely supernova remnant candidates by their physical shapes and the three of all having [SII]/Hα ratio larger than 0.4, found with T100 photometric observations, are considered to be supernova remnant candidates. Comprehensive optical imaging and spectroscopic observations with multi-wavelength observations will help us to identify the types of all these galactic candidates, more precisely.
