Stream Members Only: Data-Driven Characterization of Stellar Streams with Mixture Density Networks
Nathaniel Starkman, Jacob Nibauer, Jo Bovy +4
Stellar streams are sensitive probes of the Milky Way's gravitational potential. The mean track of a stream constrains global properties of the potential, while its fine-grained su…
Towards an astronomical foundation model for stars with a Transformer-based model
Henry W. Leung, Jo Bovy
Rapid strides are currently being made in the field of artificial intelligence using Transformer-based models like Large Language Models (LLMs). The potential of these methods for…
Decoding the age-chemical structure of the Milky Way disk: An application of Copulas and Elicitable Maps
Aarya A. Patil, Jo Bovy, Sebastian Jaimungal +2
In the Milky Way, the distribution of stars in the vs. and vs. age planes holds essential information about the history of sta…
The stellar mass of the Gaia-Sausage/Enceladus accretion remnant
James Lane, Jo Bovy, Ted Mackereth
The \textit{Gaia}-Sausage/Enceladus (GS/E) structure is an accretion remnant which comprises a large fraction of the Milky Way's stellar halo. We study GS/E using high-purity sampl…
Disentangling Stellar Age Estimates from Galactic Chemodynamical Evolution
Jeff Shen, Joshua S. Speagle, J. Ted Mackereth +2
Stellar ages are key for determining the formation history of the Milky Way, but are difficult to measure precisely. Furthermore, methods that use chemical abundances to infer ages…
Constraints on the Galactic Centre environment from \textit{Gaia} hypervelocity stars III: Insights on a possible companion to Sgr A*
Fraser A. Evans, Alexander Rasskazov, Amber Remmelzwaal +4
We consider a scenario in which Sgr A* is in a massive black hole binary (MBHB) with an as-of-yet undetected supermassive or intermediate-mass black hole companion. Dynamical encou…
