Abstract

We complement the MALATANG sample of dense gas in nearby galaxies with archival observations of $^{12}\rm CO$ and its isotopologues to determine scaling relations between Wide-field Infrared Survey Explorer (WISE) 12 $\mu$m emission and molecular gas tracers at sub-kiloparsec scales. We find that 12 $\mu$m luminosity is more tightly correlated with $^{12}\rm CO$ than it is with $^{13}\rm CO$ or dense gas tracers. Residuals between predicted and observed $^{12}\rm CO$ are only weakly correlated with molecular gas mass surface density ($\Sigma_{\rm mol}$) in regions where $\Sigma_{\rm mol}$ is very low ($\sim 10~{\rm M_{\odot}~pc^{-2}}$). Above this limit, the $^{12}\rm CO$ residuals show no correlations with physical conditions of molecular gas, while $^{13}\rm CO$ residuals depend on the gas optical depth and temperature. By analyzing differences from galaxy to galaxy, we confirm that the $^{12}\rm CO$-12 $\mu$m relation is strong and statistically robust with respect to star forming galaxies and AGN hosts. These results suggest that WISE 12 $\mu$m emission can be used to trace total molecular gas instead of dense molecular gas, likely because polycyclic aromatic hydrocarbons (PAHs, a major contributor to WISE 12 $\mu$m~emission) may be well-mixed with the gas that is traced by $^{12}\rm CO$. We propose that WISE 12 $\mu$m luminosity can be used to estimate molecular gas surface density for statistical analyses of the star formation process in galaxies., Comment: 16 pages, 7 figures, accepted for publication in ApJ

Abstract

Objective: A method for the preparation and determination of amino-mebendazole matrix reference material in eel muscle powder was established. Methods: A positive sample was obtained by culturing eels with mebendazole and was prepared into amino-mebendazole matrix reference material, which went through freeze-drying, vacuum packaging, and radiation sterilization in turn. And its homogeneity, stability, cooperative setting value, and uncertainty were examined. Results: This matrix reference material has good uniformity and can adapt to low temperatures, normal temperatures, long-distance transportation, and other environments. It can be stored for more than 12 months under -18 ℃. The characteristic value of amino-methylimidazole is （35.3±6.4） μg/kg（k=2） through the collaborative setting of 8 qualification inspection institutions. Conclusion: This matrix reference material meets the technical requirements of national standard samples and can meet the needs of quality control and method validation for amino-mebendazole residue detection in eel muscle. This study can provide a good reference for the development of food matrix reference materials.
