Abstract



We present a catalog of clouds identified from the (CO)-C-12 (1-0) data of M83, which was observed using the Atacama Large Millimeter/submillimeter Array with a spatial resolution of similar to 46 pc and a mass sensitivity of similar to 10(4)M(circle dot) (3 sigma). The almost full-disk coverage and high sensitivity of the data allowed us to sample 5724 molecular clouds with a median mass of similar to 1.9 <bold>x</bold> 10(5)M(circle dot), which is comparable to the most frequently sampled mass of giant molecular clouds by surveys in the Milky Way (MW). About 60% of the total CO luminosity in M83's disk arises from clouds more massive than 10(6)M(circle dot). Such massive clouds comprise 16% of the total clouds in number and tend to concentrate toward the arm, bar, and center, while smaller clouds are more prevalent in interarm regions. Most >10(6)M(circle dot) clouds have peak brightness temperatures T-peak above 2 K with the current resolution. Comparing the observed cloud properties with the scaling relations determined by P. M. Solomon et al. (1987, hereafter S87), T-peak > 2 K clouds follow the relations, but T-peak < 2 K clouds, which are dominant in number, deviate significantly. Without considering the effect of beam dilution, the deviations would suggest modestly high virial parameters (median alpha(vir) similar to 2.7) and low surface mass densities (median Sigma similar to 22 M-circle dot pc(-2)) for the entire cloud samples, which are similar to values found for the MW clouds by T. S. Rice et al. (2016) and M.-A Miville-Desch & ecirc;nes et al. (2017). However, once beam dilution is taken into account, the observed alpha(vir) and Sigma for a majority of the clouds (mostly T-peak <2 K) can be potentially explained with intrinsic Sigma of similar to 100 M-circle dot pc(-2) and alpha(vir) of similar to 1, which are similar to the clouds of S87.
