SRT radio image of Kes 73 at 24.8 GHz with contour levels of the ¹²CO emission superposed. The ¹²CO emission is integrated on the 85–96 km s^–1 velocity interval, and the white, light grey, and grey contours correspond to the temperature levels at 70, 100, and 120 K, respectively. The orange circle marks the extraction region we used to estimate the whole flux density of Kes 73 on our K-band maps, and the red cross the centroid of the Fermi-LAT γ-ray source. The yellow diamonds indicate the YSOs from the SPICY catalogue.
