Description
In this work, we present updated results on an ongoing dark matter search using astrometric weak gravitational lensing. Following the analysis in Mondino et al. (2020), results are reported on a dark matter search using proper motions on stars in the Magellanic Clouds from Gaia's most recent data release. Additionally, we assess our method on star-star lensing, and introduce a parallax template method to aid in the dark matter search. Finally, we provide preliminary sensitivity estimates for an acceleration-based search for compact dark matter structures.
