Keeping Time in the Milky Way with Chemical Clocks
Stellar ages are notoriously difficult to determine. However, today’s authors investigate a promising new method of estimating stellar age with “chemical clocks!”
Disentangling Milky Way Evolution with Disentangled Representation Learning, a New Tool for Chemical Tagging
Chemical tagging without chemical abundances? Today’s authors devise a neural network that ‘disentangles’ chemical abundances from stellar spectra to avoid the uncertainties that often beset chemical taggers.
Searching for Milky Way Intermediate-Mass Black Holes with Hypervelocity Stars
The search for the elusive intermediate-mass black hole continues. Today’s authors present a novel method to search for Milky Way intermediate-mass black holes with the hyper-velocity stars they eject!
