A Search For Stellar-mass Black Holes Via Astrometric Microlensing II: 2012-2015 Keck Candidates
Mace J. Huston, Jessica R. Lu, Casey Y. Lam +58
The Milky Way is expected to host 10 stellar-mass black holes with an uncertain binary fraction. The only proven method to detect isolated stellar mass black holes is gra…
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…
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,…
