Mass Measurements of Isolated Objects from Space-based Microlensing

Wei Zhu, S. Calchi Novati, A. Gould +78

We report on the mass and distance measurements of two single-lens events from the 2015 \emph{Spitzer} microlensing campaign. With both finite-source effect and microlens parallax…

Spitzer Microlens Measurement of a Massive Remnant in a Well-Separated Binary

Y. Shvartzvald, A. Udalski, A. Gould +63

We report the detection and mass measurement of a binary lens OGLE-2015-BLG-1285La,b, with the more massive component having (80% probability). A main-sequence…

OGLE-2013-BLG-0578L: Microlensing Binary Composed of A Brown Dwarf And An M Dwarf

H. Park, A. Udalski, C. Han +9

Determining physical parameters of binary microlenses is hampered by the lack of information about the angular Einstein radius due to the difficulty of resolving caustic crossings.…

Spitzer as Microlens Parallax Satellite: Mass and Distance Measurements of Binary Lens System OGLE-2014-BLG-1050L

Wei Zhu, A. Udalski, A. Gould +26

We report the first mass and distance measurement of a caustic-crossing binary system OGLE-2014-BLG-1050L using the space-based microlens parallax method. \emph{Spitzer} captured t…

Candidate Gravitational Microlensing Events for Future Direct Lens Imaging

C. B. Henderson, H. Park, T. Sumi +76

The mass of the lenses giving rise to Galactic microlensing events can be constrained by measuring the relative lens-source proper motion and lens flux. The flux of the lens can be…

Interpretation of a Short-Term Anomaly in the Gravitational Microlensing Event MOA-2012-BLG-486

K. -H. Hwang, J. -Y. Choi, I. A. Bond +78

A planetary microlensing signal is generally characterized by a short-term perturbation to the standard single lensing light curve. A subset of binary-source events can produce per…
