Detection of colour variations from gravitational microlensing observations in the quadruple quasar HE0435-1223: Implications for the accretion disc

Astronomy & Astrophysics
We present monitoring observations of quasar microlensing in the quadruple quasar HE0435-1223. The microlensing-induced light curves of the quasar images are chromatic, i.e. they depend on the applied filter band. Comparison with microlensing simulations

Exoplanet Detection Techniques: From Classical Methods to Modern Machine Learning Approaches

Theoretical and Natural Science
Since the discovery of 51 Pegasi b in 1995, exoplanet research has evolved from serendipitous radial-velocity detections to large-scale surveys employing transit photometry, microlensing, astrometry, and high-contrast direct imaging.

Calculation of ephemerides of gravitational microlensing events based on Gaia data

Publications of the Pulkovo_Observatory
Observations of gravitational lensing and microlensing events have become a routine part of modern astronomy. The analysis of these phenomena provides crucial information for addressing a wide range of astrophysical problems — from studying the ...

The First Model-independent Chromatic Microlensing Search: No Evidence in the Gravitational Wave Catalog of LIGO–Virgo–KAGRA

Astrophysical Journal
The lensing of gravitational waves (GWs) due to intervening matter distribution in the Universe can lead to chromatic and achromatic signatures in the wave-optics and geometrical-optics limit, respectively.
