Dark lens candidates from Gaia Data Release 3
K. KruszyÅska, Å. Wyrzykowski, K. A. Rybicki +48
Gravitational microlensing is a phenomenon that allows us to observe dark remnants of stellar evolution even if they no longer emit electromagnetic radiation. In particular, it can…
Lens mass estimate in the Galactic disk extreme parallax microlensing event Gaia19dke
M. MaskoliÅ«nas, Å. Wyrzykowski, K. Howil +74
We present the results of our analysis of Gaia19dke, an extraordinary microlensing event in the Cygnus constellation that was first spotted by the {\gaia} satellite. This event fea…
Lens parameters for Gaia18cbf -- a long gravitational microlensing event in the Galactic plane
Katarzyna KruszyÅska, Å. Wyrzykowski, K. A. Rybicki +29
Context: The timescale of a microlensing event scales as a square root of a lens mass. Therefore, long-lasting events are important candidates for massive lenses, including black h…
Gaia22dkvLb: A Microlensing Planet Potentially Accessible to Radial-Velocity Characterization
Zexuan Wu, Subo Dong, Tuan Yi +50
We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensin…
Uncovering the Invisible: A Study of Gaia18ajz, a Candidate Black Hole Revealed by Microlensing
K. Howil, Å. Wyrzykowski, K. KruszyÅska +30
Identifying black holes is essential for comprehending the development of stars and uncovering novel principles of physics. Gravitational microlensing provides an exceptional oppor…
A close binary lens revealed by the microlensing event Gaia20bof
E. Bachelet, P. Rota, V. Bozza +24
During the last 25 years, hundreds of binary stars and planets have been discovered towards the Galactic Bulge by microlensing surveys. Thanks to a new generation of large-sky surv…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Å. Wyrzykowski, P. J. MikoÅajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
