First assessment of the binary lens OGLE-2015_BLG-0232

E. Bachelet, V. Bozza, C. Han +51

We present an analysis of the microlensing event OGLE-2015-BLG-0232. This event is challenging to characterize for two reasons. First, the light curve is not well sampled during th…

Discovery of two quasars at from the OGLE Survey

Szymon Kozłowski, Eduardo Bañados, A. Udalski +16

We have used deep Optical Gravitational Lensing Experiment (OGLE-IV) images ( mag, mag at ) of the Magellanic System, encompassing an area of $\s…

Rotation curve of the Milky Way from Classical Cepheids

P. Mroz, A. Udalski, D. M. Skowron +7

Flat rotation curves of spiral galaxies are considered as an evidence for dark matter, but the rotation curve of the Milky Way is difficult to measure. Various objects were used to…

OGLE-2015-BLG-1670Lb: A Cold Neptune beyond the Snow Line in the Provisional WFIRST Microlensing Survey Field

Clément Ranc, David P. Bennett, Yuki Hirao +56

We present the analysis of the microlensing event OGLE-2015-BLG-1670, detected in a high-extinction field, very close to the Galactic plane. Due to the dust extinction along the li…

A three-dimensional map of the Milky Way using classical Cepheid variable stars

D. M. Skowron, J. Skowron, P. Mróz +9

The Milky Way is a barred spiral galaxy, with physical properties inferred from various tracers informed by the extrapolation of structures seen in other galaxies. However, the dis…

Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-Rotating Low-Mass Brown Dwarf

Yossi Shvartzvald, Jennifer C. Yee, Jan Skowron +63

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 ca…
