Overview of the G28 region. Left panel: color scale showing GLIMPSE 8 μm emission (Churchwell et al. 2009) for the G28 IRDC. The contours show the corresponding ATLASGaL 870 μm dust continuum emission, starting at 4σ (200 mJy beam⁻¹) (Schuller et al. 2009) and continuing in 8σ steps. The box outlines the area shown to the right. Right panel: zoom into the G28 target region. The color scale presents the velocity field (first moment) km s⁻¹ observed in ¹³CO(3–2) with APEX (Beuther et al. 2020). The contours show the 870 μm continuum emission from the ATLASGAL survey (Schuller et al. 2009). The red circles outline the observed NOEMA mosaic. A scale bar is shown to the right in both panels.
