Abstract (from CDS):

We analyze the relationship between maximum cluster mass Mmaxand surface densities of total gas (Σgas), molecular gas (Σgas), and star formation rate (ΣSFR) in the flocculent galaxy M 33, using published gas data and a catalog of more than 600 young star clusters in its disk. By comparing the radial distributions of gas and most massive cluster masses, we find that Mmax∝Σ4.7±0.4gas, Mmax∝Σ^1.3 ±0.1^H2, and Mmax∝Σ1.0±0.1SFR. We rule out that these correlations result from the size of the sample; hence, the change of the maximum cluster mass must be due to physical causes.
