A Simulation of the Milky Way with a Decelerating Bar

Three projected spatial distributions of test particles after four billion years in the decelerating-bar simulation.

Spatial distribution of test particles after 4 Gyr of evolution in the simulation.

Observed and resampled simulated spatial distributions compared across three projected planes.

Observed spatial distribution and the corresponding simulation sample after three-dimensional resampling to match the observational selection in position space.

Neural-network-selected observed and simulated samples compared across three projected planes.

Observed and resampled simulated samples after applying the neural-network classifier, showing the selected component in three projected planes.
