Microlensify: a Transformer Based Machine Learning Classifier for Microlensing Events Trained on TESS Light Curves

Atousa Kalantari, Somayeh Khakpash, Sedighe Sajadian +3

Microlensing can reveal populations of faint compact objects that are otherwise difficult to detect. Depending on their design, all-sky surveys have the potential to search for the…

Wavelet transforms of microlensing data: Denoising, extracting intrinsic pulsations, and planetary signals

Sedighe Sajadian, Hossein Fatheddin

Wavelets are waveform functions that describe transient and unstable variations, such as noises. In this work, we study the advantages of discrete and continuous wavelet transforms…

Numerically studying the degeneracy problem in extreme finite-source microlensing events

Sedighe Sajadian

Most transit microlensing events due to very low-mass lens objects suffer from extreme finite-source effects. While modeling their light curves, there is a known continuous degener…

Improved Aberth-Ehrlich root-finding algorithm and its further application for Binary Microlensing

Hossein Fatheddin, Sedighe Sajadian

In gravitational microlensing formalism and for modeling binary light curves, the key step is solving the binary lens equation. Currently, a combination of the Newton's and Laguerr…

Polarization in caustic-crossing binary microlensing events

Sedighe Sajadian

Here, we revisit the polarization signal in caustic-crossing binary microlensing and introduce the maps of the polarization signals of the source star as a function of its position…

Prediction on detection and characterization of Galactic disk microlensing events by LSST

Sedighe Sajadian, Radoslaw Poleski

Upcoming LSST survey gives an unprecedented opportunity for studying populations of intrinsically faint objects using microlensing technique. Large field of view and aperture allow…

The advantages of using a Lucky Imaging camera for observations of microlensing events

Sedighe Sajadian, Sohrab Rahvar, Martin Dominik +1

In this work, we study the advantages of using a Lucky Imaging camera for the observations of potential planetary microlensing events. Our aim is to reduce the blending effect and…

Orbital motion effects in astrometric microlensing

Sedighe Sajadian

We investigate lens orbital motion in astrometric microlensing and its detectability. In microlensing events, the light centroid shift in the source trajectory (the astrometric tra…
