Multiwavelength view (galactic coordinates orientation) of the group of H ii regions (G351.65+0.51, G351.69+0.67, G351.68+0.61, and G351.766+0.492). Blue dashed circles indicate the radio sources while the green and yellow circles underline the 8 μm bubbles. The lower-right image combines Spitzer-8 μm (green) and WISE-22 μm (red) images. The magenta isocontours underline the Hα emission. Similar to Gvaramadze et al. (2011), the bow-shock aspect of G351.65+0.51 can be seen on the WISE-22 μm image (red arrow in the upper-right panel).
