Multiwavelength emissions toward the Bubble region of N11 by ALMA and eROSITA. (a) Optical image with Hα (red), SII (green), and [OIII] (blue). (b) Spatial distributions of ALMA¹²CO (J = 2−1) in green overlaid with the optical image. The spatial distribution of X-ray emissions with a velocity range of (c) 0.5–0.7 keV and (d) 1.0–2.0 keV. The green circle is SNR N11L (Maggi et al. 2016). No other SNR is observed by the latest ASKAP radio data in the whole region (Bozzetto et al. 2023). The black crosses and asterisks are O-type stars and WR stars (Bonanos et al. 2009), respectively. The boxes in (b), (c), and (d) represent the observation areas of ALMA, with the yellow discussed in Sect. 5.1.4.
