First Direct Identification of a Multi-Star Microlens System Hosting a Planet
Sean K. Terry, David P. Bennett, Jean-Philippe Beaulieu +11
Nearly 25 years have passed since gravitational microlensing delivered its first exoplanet discoveries. The relative proper motion between lens and source systems allows them to be…
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…
Limits on a Host Star around a Saturn-mass Free-floating Planet Candidate KMT-2024-BLG-0792/OGLE-2024-BLG-0516
Przemek Mróz, Klara Piotrowska, Antoine Mérand +2
Recent studies found a number of short-timescale microlensing events that are thought to be produced by free-floating or wide-orbit planets. The microlensing event KMT-2024-BLG-079…
KMT-2025-BLG-0975Lb and KMT-2025-BLG-1160Lb: Two Uranus-Mass Planets Beyond the Snow Line Discovered by Microlensing
Cheongho Han, Chung-Uk Lee, Andrzej Udalski +27
We present the analysis of two planetary microlensing events, KMT-2025-BLG-0975 and KMT-2025-BLG-1160, discovered during the 2025 Galactic bulge microlensing season through high-ca…
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…
Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey. IV. Lens Mass and Distance Measurements
Sean K. Terry, Etienne Bachelet, Farzaneh Zohrabi +54
As part of the Galactic Bulge Time Domain Survey (GBTDS), the Nancy Grace Roman Galactic Exoplanet Survey (RGES) will use microlensing to discover cold outer planets and free-float…
Eppur non si trovano: Comments on the Primordial Black Hole Limits in the Galactic Halo
P. Mróz, A. Udalski, M. K. Szymański +13
In a recent arXiv post, Hawkins & Garcia-Bellido raised doubts on the results of 20-yr long OGLE photometric monitoring, which did not find a large number of gravitational microlen…
Microlensing optical depth, event rate, and limits on compact objects in dark matter based on 20 yr of OGLE observations of the Small Magellanic Cloud
P. Mróz, A. Udalski, M. K. Szymański +12
Some previous studies have suggested that massive and intermediate-mass primordial black holes (PBHs) could comprise a substantial fraction of dark matter in the Universe. Such bla…
Exoplanet Occurrence Rates from Microlensing Surveys
P. Mroz, R. Poleski
The number of exoplanets detected using gravitational microlensing technique is currently larger than 200, which enables population studies. Microlensing is uniquely sensitive to l…
Measuring the mass function of isolated stellar remnants with gravitational microlensing. I. Revisiting the OGLE-III dark lens candidates
P. Mroz, L. Wyrzykowski
Gravitational microlensing may detect dark stellar remnants - black holes or neutron stars - even if they are isolated. However, it is challenging to estimate masses of isolated da…
Measuring the mass function of isolated stellar remnants with gravitational microlensing. II. Analysis of the OGLE-III data
P. Mroz, A. Udalski, L. Wyrzykowski +5
Our knowledge of the birth mass function of neutron stars and black holes is based on observations of binary systems but the binary evolution likely affects the final mass of the c…
A Gravitationally Lensed Quasar Discovered in OGLE
Z. Kostrzewa-Rutkowska, S. Kozłowski, C. Lemon +15
We report the discovery of a new gravitationally lensed quasar (double) from the Optical Gravitational Lensing Experiment (OGLE) identified inside the 670 sq. deg area encomp…
The OGLE Collection of Variable Stars. Classical Cepheids in the Magellanic System
I. Soszynski, A. Udalski, M. K. Szymanski +10
We present here a nearly complete census of classical Cepheids in the Magellanic System. The sample extends the set of Cepheids published in the past by the Optical Gravitational L…
One Thousand New Dwarf Novae from the OGLE Survey
P. Mroz, A. Udalski, R. Poleski +7
We present one of the largest collections of dwarf novae (DNe) containing 1091 objects that have been discovered in the long-term photometric data from the Optical Gravitational Le…
Eclipsing Binaries with Classical Cepheid Component in the Magellanic System
A. Udalski, I. Soszyński, M. K. Szymański +10
We present a census of eclipsing binary systems with classical Cepheid as a component. All such systems known were found in the OGLE collection of classical Cepheids in the Magella…
Over 38000 RR Lyrae Stars in the OGLE Galactic Bulge Fields
I. Soszynski, A. Udalski, M. K. Szymanski +10
We present the most comprehensive picture ever obtained of the central parts of the Milky Way probed with RR Lyrae variable stars. This is a collection of 38257 RR Lyr stars detect…
Large Variety of New Pulsating Stars in the OGLE-III Galactic Disk Fields
P. Pietrukowicz, W. A. Dziembowski, P. Mroz +10
We present the results of a search for pulsating stars in the 7.12 deg^2 OGLE-III Galactic disk area in the direction tangent to the Centaurus Arm. We report the identification of…
