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…

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…

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…
