Goodbye to Chi by Eye: A Bayesian Analysis of Photometric Binaries in Six Open Clusters
We present a robust methodology for identifying photometric binaries in star clusters. Using
Gaia DR3, Pan-STARRS, and Two Micron All Sky Survey data, we self-consistently define …

Leveraging single-case results to Bayesian hierarchical modelling
In scientific research, we often aim to learn one or more parameters of instances (objects)
from a population—such as the batting averages of a group of baseball players and …
