Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia

U. Pylypenko, Ł. Wyrzykowski, P. J. Mikołajczyk +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…

Astrometry-Only Detection of Microlensing Events with Gaia

T. Jankovič, A. Gomboc, Ł. Wyrzykowski +7

Astrometric microlensing events occur when a massive object passes between a distant source and the observer, causing a shift of the light centroid. The precise astrometric measure…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

Dark lens candidates from Gaia Data Release 3

K. Kruszyńska, Ł. 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. Maskoliūnas, Ł. 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…

Is there a nearby microlensing stellar remnant hiding in Gaia DR3 astrometry?

Maja Jabłońska, Łukasz Wyrzykowski, Krzysztof A. Rybicki +3

Massive galactic lenses with large Einstein Radii should cause a measurable astrometric microlensing effect, i.e. the light centroid shift due to the motion of the two images. Such…

Dark lenses through the dust: parallax microlensing events in the VVV

Zofia Kaczmarek, Peter McGill, N. Wyn Evans +4

We use near-infrared photometry and astrometry from the VISTA Variables in the Via Lactea (VVV) survey to analyse microlensing events containing annual microlensing parallax inform…
