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…
Incorporating physical source parameters into microlensing modeling
Mateusz J. Mróz, Radosław Poleski, Andrzej Udalski +14
Modeling of complex microlensing events suffers from many difficult-to-disentangle degeneracies. This is especially the case for orbital motion of the source in a binary system, th…
A free-floating-planet microlensing event caused by a Saturn-mass object
Subo Dong, Zexuan Wu, Yoon-Hyun Ryu +39
A population of free-floating planets is known from gravitational microlensing surveys. None have a directly measured mass, owing to a degeneracy with the distance, but the populat…
An Extremely Hot Pulsating Pre-White Dwarf from OGLE
P. Pietrukowicz, K. Werner, M. J. Mroz +1
We show that the blue 18.3-minute variable object discovered in the Galactic disk by the OGLE-III survey and named OGLE-GD-WD-0001 is a pulsating pre-white dwarf of PG 1159 spectra…
Limits on planetary-mass primordial black holes from the OGLE high-cadence survey of the Magellanic Clouds
Przemek Mróz, Andrzej Udalski, Michał K. Szymański +11
Observations of the Galactic bulge revealed an excess of short-timescale gravitational microlensing events that are generally attributed to a large population of free-floating or w…
Observations of Microlensed Images with Dual-field Interferometry: On-sky Demonstration and Prospects
P. Mroz, S. Dong, A. Merand +57
Interferometric observations of gravitational microlensing events offer an opportunity for precise, efficient, and direct mass and distance measurements of lensing objects, especia…
OGLE-2014-BLG-0221Lb: A Jupiter Mass Ratio Companion Orbiting either a Late-Type Star or a Stellar Remnant
Rintaro Kirikawa, Takahiro Sumi, David P. Bennett +33
We present the analysis of microlensing event OGLE-2014-BLG-0221, a planetary candidate event discovered in 2014. The photometric light curve is best described by a binary-lens sin…
