A Differentiable Binary Microlensing Model Using Adaptive Contour Integration Method

The Astronomical Journal
We present microlux , which is a Jax -based code that can compute the binary microlensing light curve and its derivatives both efficiently and accurately.

Simulations of gravitational microlensing [PDF]

, 2011
Gravitational microlensing occurs when a massive lens (typically a star) deflects light from a more distant source, creating two unresolvable images that are magnified.

Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey

Astronomy & Astrophysics
Context. The Nancy Grace Roman Space Telescope will expand the reach of gravitational microlensing surveys by increasing the number of events monitored and the precision of their light curves. Aims.

Observations of Microlensed Images with Dual-field Interferometry: On-sky Demonstration and Prospects

The Astrophysical Journal
Interferometric observations of gravitational microlensing events offer an opportunity for precise, efficient, and direct mass and distance measurements of lensing objects, especially those of isolated neutron stars and black holes.

Residual Test to Search for Microlensing Signatures in Strongly Lensed Gravitational Wave Signals

The Astrophysical Journal
When a gravitational wave signal encounters a massive object, such as a galaxy or galaxy cluster, it undergoes strong gravitational lensing, producing multiple copies of the original signal.

Testing General Relativity with Binary Lens Microlensing Events

The Astrophysical Journal Letters
Einstein’s General Relativity (GR), which has been precisely tested on galaxy and solar system scales, is still poorly constrained in extremely weak gravitational fields (with dimensionless Newtonian potentials of Φ ∼ 10 ^−8 ). In this Letter, we propose

Microlensing Parallax for Observers in Heliocentric Motion [PDF]

, 2016
Motivated by the ongoing Spitzer observational campaign, and the forthcoming K2 one, we revisit, working in an heliocentric reference frame, the geometrical foundation for the analysis of the microlensing parallax, as measured with the simultaneous ...

Modeling Binary Lenses and Sources with the BAGLE Python Package

The Astrophysical Journal
Gravitational microlensing is a powerful tool that can be used to find and measure the mass of isolated and dark compact objects. In many microlensing events, the lens, the source, or both may be binary systems.
