Morphology of G11P1-HFS seen in the Spitzer, JWST, and ALMA observations. a) Spitzer 8 μm image. b) Two-color composite map made of the JWST ratio map (F444W/F356W; inverted scale in red) and Spitzer 8 μm (cyan) emission. Stars show the positions of compact radio continuum sources from Rosero et al. (2014). c) ALMA N₂H⁺(1–0) integrated emission map overlaid with the footprints of structures seen in the JWST ratio map (see text for details). The color scale bar has a unit of Jy beam⁻¹ km s⁻¹. In each panel, a cross represents the position of the 6.7-GHz methanol maser. A dotted contour in panels “b” and “c” mark the Spitzer 8 μm emission feature. In panels “b” and “c”, arrows highlight possible filamentary features (F1–F6). Scale bar represents a physical scale of 0.3 pc at a distance of Galactic Snake (2.92 kpc; Dewangan et al. 2024).
