Black hole astrometric binaries in the Roman Galactic Bulge Time Domain Survey
Casey Y. Lam, Jessica R. Lu, Kareem El-Badry +6
The Nancy Grace Roman Space Telescope (Roman), NASA's next flagship mission, is currently scheduled to launch in August 2026. As part of its mission, Roman will conduct the Galacti…
Charting the Galactic Underworld I: Comprehensive simulations of the kinematics, rates, and demographics of Milky Way black holes
Tom Wagg, Katelyn Breivik, Adrian M. Price-Whelan +3
With upcoming data from Roman, Gaia DR4, and spectroscopic surveys, we will soon have an unprecedented dataset of Milky Way black holes (BHs) to constrain their formation and evolu…
Expanding the SPISEA Stellar Population Synthesis Software to the Substellar Regime
Caitlin Begbie, Rachel Street, Katarzyna Kruszynska +4
We present an extension of the SPISEA stellar population synthesis framework that adds brown dwarfs to the existing range of stellar mass objects, enabling physically consistent mo…
The BAGLE Python Package for Bayesian Analysis of Gravitational Lensing Events
J. R. Lu, M. Medford, C. Y. Lam +8
We present the open-source Python package, BAGLE (Bayesian Analysis of Gravitational Lensing Events), which enables modeling and joint fitting of photometric and astrometric data s…
Modeling Binary Lenses and Sources with the BAGLE Python Package
T. Dex Bhadra, J. R. Lu, Natasha S. Abrams +4
Gravitational microlensing is a powerful tool that can be used to find and measure the mass of isolated and dark compact objects. In many microlensing events, the lens, the source,…
