OGLE-2017-BLG-1130: The First Binary Gravitational Microlens Detected From Spitzer Only
We analyze the binary gravitational microlensing event OGLE-2017-BLG-1130 (mass ratio q~0.45), the first published case in which the binary anomaly was only detected by the Spitzer Space Telescope. This event provides ...
OGLE-2017-BLG-0329L: A Microlensing Binary Characterized with Dramatically Enhanced Precision Using Data from Space-based Observations
Mass measurements of gravitational microlenses require one to determine the microlens parallax PIe, but precise PIe measurement, in many cases, is hampered due to the subtlety of the microlens-parallax signal combined ...
Spitzer Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-Rotating Low-Mass Brown Dwarf
The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it can measure both the mass and five of the ...
