An Updated SynthPop Model for Microlensing Simulations I: Model Description & Evaluation

Macy J. Huston, Alison L. Crisp, Marz Newman +21

The optimization and interpretation of microlensing surveys depends on having an accurate model of the Milky Way. However, existing population synthesis Galactic modeling tools oft…
