Context. Due to their scarcity, microlensing events in the Galactic disk are of great interest
and high-cadence photometric observations, supplemented by spectroscopic follow-up, are …

Context. Microlensing provides a unique opportunity to detect non-luminous objects. In the
rare cases that the Einstein radius θ E and microlensing parallax π E can be measured, it is …

Context. Gravitational microlensing is a method that is used to discover planet-hosting
systems at distances of several kiloparsec in the Galactic disk and bulge. We present the …

Context. Astrometric gravitational microlensing is an excellent tool to determine the mass of
stellar objects. Using precise astrometric measurements of the lensed position of a …

Context. Astrometric microlensing can be used to make precise measurements of the
masses of lens stars that are independent of their assumed internal physics. Such direct …

During the last 25 yr, hundreds of binary stars and planets have been discovered toward the
Galactic bulge by microlensing surveys. Thanks to a new generation of large-sky surveys, it …

Gaia16aye was a binary microlensing event discovered in the direction towards the northern
Galactic disc and was one of the first microlensing events detected and alerted to by the …

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 …

Context. One of the rarest types of variability is the phenomenon of gravitational
microlensing, a transient brightening of a background star due to an intervening lensing …

Gravitational microlensing is a phenomenon that allows us to observe the dark remnants of
stellar evolution, even if these bodies are no longer emitting electromagnetic radiation. In …
