Corrected dust-mass opacity in the LMC: histogram of extinction-corrected dust-mass opacity (κ160) values for all ISM regions measured in the LMC. Compared to existing literature measurements of κ160, both in the LMC and SMC (e.g., K. D. Gordon et al. 2014, 2017; J. Roman-Duval et al. 2017) and beyond (e.g., M101, 22 other galaxies; C. J. R. Clark et al. 2016; I.-D. Chiang et al. 2018, respectively), these new inferred measurements span broader values (κ160 = 0.3–6 m2 kg−1). This discrepancy can be explained by the fact that the observed fields probe a wide range of ISM environments (ΣH = 4–100 M⊙ pc−2), especially compared to previous surveys that are often biased by measuring κD toward brighter, higher column-density regions of galaxies.
