Filamentary Shell Structures From The Aao/Ukst Ha Survey, Andrew Walker, William Zealey, Q A. Parker

Faculty of Engineering and Information Sciences - Papers: Part A

Here we present the first results of a search for new optical supernova remnant candidates and other filamentary objects on films produced by the Anglo-Australian Observatory/UK Schmidt Telescope Há Survey. Sixty-one fields, or 26% of the Galactic plane survey fields, have been visually examined. This has resulted in the detection of four newlarge diameter filamentary structures, and the discovery of extensive new optical emission in two previously known optical supernova remnant candidates.
