Overview of the AFGL 2591 star-forming region. The background color map shows an infrared image obtained with Gemini in the K′ band. The green contours show the 3.6 cm radio continuum emission taken from Johnston et al. (2013). The contours are drawn at levels of 3, 5, 10, 20, 40, 80, and 160σ (σ = 0.03 mJy beam⁻¹). The VLA beam size (0″. 43 × 0″. 40) is shown inthe lower left corner. The gray dashed circle indicates the primary beam of our NOEMA observations (23″).
