Multi wavelength view of the Cygnus-X star forming region. Upper panel: combination of observations at 500 μm and 8 μm from the Herschel SPIRE and MSX telescopes of the Cygnus X star-forming complex. Radiation at 500 μm (light blue scale) indicates emission from cold dust, while the 8 μm (orange scale) traces photon-dominated regions. Lower panel: continuum observations at 1.42 GHz from the Canadian Galactic Plane Survey (Taylor et al. 2003). A large fraction of this emission is likely thermal free-free radiation by material possibly ionised by Cyg OB2 (Emig et al. 2022). Colour scales are given in arbitrary units.
