Far-IR and radio images of the IRAS 22147 region. Left: three-color composite image of the IRAS 22147 region combining the Herschel/EPoS SPIRE 250 µm (red), PACS 160 µm (green), and PACS 70 µm (blue) mosaics. Right: Spitzer/MIVS 24 µm image with the VLA 1.4 GHz radio continuum contours overlaid (Green & Joncas 1994). Positions of YSO candidates identified in this work are shown in red symbols, as specified in the legend. White xs show central positions of HII regions G104.735+02.859 at 7.8 kpc (position at the arc) and G104.699+02.781 at6.6kpc (Anderson etal. 2015).
