The Two-infall Model Revisited: Constraints on Milky Way Bulge Assembly from >30,000 Galactic Chemical Evolution Models and Machine Learning
Niall Miller, Meridith Joyce, Christian I. Johnson +4
We constrain the formation history of the Milky Way bulge using a two-infall galactic chemical evolution (GCE) algorithm implemented in the N'OMEGA+ code. We recover a best-fit sce…

Empirical Globular Cluster Ridgeline Construction on Gaia Data
Anett Simon-Zsók, László Molnár, Csilla Kalup +1
We present a new method and a corresponding code to compress the color magnitude diagram of a globular cluster into a representative curve, called a ridgeline, that can be more rea…
