Quantifying Systematic Age Discrepancies in Very Young Star Clusters
Joseph Guzman, Jeremiah Murphy, Emma Beasor +5
We infer the ages of three young stellar clusters, NGC 2004, NGC 7419, and NGC 2100, using Stellar Ages, a statistical algorithm designed to infer stellar population properties fro…
Uncertainty Quantification in Bayesian Clustering
Garritt L. Page, Andrés F. Barrientos, David B. Dahl +1
Bayesian clustering methods have the widely touted advantage of providing a probabilistic characterization of uncertainty in clustering through the posterior distribution. An amazi…
The Mass of the Vela Pulsar Progenitor and the Age of the Vela-Puppis Complex
Jeremiah W. Murphy, Andres F. Barrientos, Rene Andrae +4
The association of the Vela Pulsar with the Vela Supernova Remnant has long supported the hypothesis that core-collapse supernovae yield neutron stars, but its surrounding stellar…
Stellar Ages: A Code to Infer Properties of Stellar Populations
Joseph J. Guzman, Jeremiah W. Murphy, Andres F. Barrientos +2
We present a novel statistical algorithm, Stellar Ages, which currently infers the age, metallicity, and extinction posterior distributions of stellar populations from their magnit…
