Serp-FIRS1 (Serp-SMM1/IRAS 18273+0113) region
Serp-FIRS1 (Serp-SMM1/IRAS 18273+0113) region: (a) The 4.5 μm and 24 μm HiRes deconvolved images. The MIPS 24 μm image is overlaid as contours on the IRAC 4.5 μm gray scale image. A square root color stretch is used to bring out low and high brightness emissions and the contour levels are in increments of factors of two or larger as indicated. The peak intensities (in units of MJy Sr–1) in the protostar/jet-outflow are indicated. The panels to the right show blowups of the selected regions highlighted by boxes in the left panel. The atomic jet features, traced by the atomic and/or ionic line emissions within the MIPS 24 μm band are identified by the 24 μm contours overlaid on the 4.5 μm gray scale image. Binary components are identified in the right panel. Note the associated atomic jet traced by the 24 μm emission. (b) 3-color representation of HiRes deconvolved Spitzer IRAC images: IRAC 3.6 μm (blue), 4.5 μm (green), 8.0 μm (red). In the 3-color representation the wide angle outflows are identified by the blue excess while the h2 jets and bow shocks by the green excess. X marks muxbleed artifacts in the 8 μm image.
