An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

Kailash C. Sahu, Jay Anderson, Stefano Casertano +90

We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…

OGLE-2013-BLG-0102LA,B: Microlensing binary with components at star/brown-dwarf and brown-dwarf/planet boundaries

Y. K. Jung, A. Udalski, T. Sumi +51

We present the analysis of the gravitational microlensing event OGLE-2013-BLG-0102. The light curve of the event is characterized by a strong short-term anomaly superposed on a smo…

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…

Using Orbital Effects to Break the Close/wide Degeneracy in Binary-lens Microlensing Events

I. -G. Shin, T. Sumi, A. Udalski +37

Microlensing can provide an important tool to study binaries, especially those composed of faint or dark objects. However, accurate analysis of binary-lens light curves is often ha…

Microlensig Binaries with Candidate Brown Dwarf Companions

I. -G. Shin, C. Han, A. Gould +152

Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation history. In this pa…

Characterizing Lenses and Lensed Stars of High-Magnification Single-lens Gravitational Microlensing Events With Lenses Passing Over Source Stars

J. -Y. Choi, I. -G. Shin, S. -Y. Park +148

We present the analysis of the light curves of 9 high-magnification single-lens gravitational microlensing events with lenses passing over source stars, including OGLE-2004-BLG-254…

OGLE-2009-BLG-023/MOA-2009-BLG-028: Characterization of a Binary Microlensing Event Based on Survey Data

K. -H. Hwang, C. Han, A. Udalski +37

We report the result of the analysis of the light curve of a caustic-crossing binary-lens microlensing event OGLE-2009-BLG-023/MOA-2009-BLG-028. Even though the event was observed…

Binary microlensing event OGLE-2009-BLG-020 gives a verifiable mass, distance and orbit predictions

J. Skowron, A. Udalski, A. Gould +99

We present the first example of binary microlensing for which the parameter measurements can be verified (or contradicted) by future Doppler observations. This test is made possibl…

OGLE-2005-BLG-153: Microlensing Discovery and Characterization of A Very Low Mass Binary

K. -H. Hwang, A. Udalski, C. Han +77

The mass function and statistics of binaries provide important diagnostics of the star formation process. Despite this importance, the mass function at low masses remains poorly kn…

OGLE 2008--BLG--290: An accurate measurement of the limb darkening of a Galactic Bulge K Giant spatially resolved by microlensing

P. Fouque, D. Heyrovsky, S. Dong +115

Gravitational microlensing is not only a successful tool for discovering distant exoplanets, but it also enables characterization of the lens and source stars involved in the lensi…
