Using the star formation histories (SFHs) near 94 supernova remnants (SNRs),we infer the progenitor mass distribution for core-collapse supernovae. We useBayesian inference and model each SFH with multiple bursts of star formation(SF), one of which is assumed to be associated with the SNR. Assumingsingle-star evolution, the minimum mass of CCSNe is $7.33^{+0.02}_{-0.16}$$\text{M}_\odot$, the slope of the progenitor mass distribution is $\alpha =-2.96^{+0.45}_{-0.25}$, and the maximum mass is greater than$\text{M}_\textrm{max} > 59$ $\text{M}_\odot$ with a 68% confidence. Whilethese results are consistent with previous inferences, they also providetighter constraints. The progenitor distribution is somewhat steeper than aSalpeter initial mass function ($\alpha$ = -2.35). This suggests that eitherSNR catalogs are biased against the youngest SF regions, or the most massivestars do not explode as easily as lower mass stars. If SNR catalogs are biased,it will most likely affect the slope but not the minimum mass. Theuncertainties are dominated by three primary sources of uncertainty, the SFHresolution, the number of SF bursts, and the uncertainty on SF rate in each agebin. We address the first two of these uncertainties, with an emphasis onmultiple bursts. The third will be addressed in future work.
