Lensing point-spread function of coherent astrophysical sources and non-trivial wave effects
Xun Shi
Most research on astrophysical lensing has been conducted using the geometric optics framework, where there exists a clear concept of lensing images. However, wave optics effects c…

Acquiring the Lefschetz thimbles: efficient evaluation of the diffraction integral for lensing in wave optics
Xun Shi
Evaluating the Kirchhoff-Fresnel diffraction integral is essential in studying wave effects in astrophysical lensing, but is often intractable because of the highly oscillatory int…
