HESS J1614−518. HI (top panels) and CO (bottom panels) intensity images toward the direction of HESS J1614−518, in velocity ranges as given on the images. HI data are from the Southern Galactic Plane Survey McClure-Griffiths et al. (2005); CO data are from Nanten (Matsunaga et al. 2001). The slices in the left two panels correspond to a location in the Sagittarius-Carina arm at a distance of 1.5 kpc, while the right two panels are from a location in the Norma-Cygnus arm at a distance of 5.5 kpc. The HI images at the velocity range of -30 km s^-1 to -12 km s^-1 indicate a possible void in the gas in directional coincidence with HESS J1614−518. At the center of this position and in compatible distance to Earth, the stellar cluster Pismis 22 is located.
