Lectures on Gravitational Lensing
read the original abstract
These lectures give an introduction to Gravitational Lensing. We discuss lensing by point masses, lensing by galaxies, and lensing by clusters and larger-scale structures in the Universe. The relevant theory is developed and applications to astrophysical problems are discussed.

Microlensing of fast and slow compact objects
Microlensing surveys constrain fast and slow compact objects at masses and densities differing by orders of magnitude from dark matter limits due to speed-mass degeneracy in Einstein crossing times.

COOL-LAMPS IX: A Rare Duo of Quasars Each Lensed by a Single Massive Galaxy Cluster
A single galaxy cluster lenses two quasars (one Type I at z=1.524, one dust-obscured Type II at z=1.939) into four images each, yielding a projected mass of ~3.3e14 solar masses within 500 kpc and time delays of hundr...

A Forward, Analytic, Differentiable, Geometric (But Inflexible) Lens Model
The SIEP+XS_|| model supplies an analytic forward mapping from source to image plane for gravitational lensing, offering large speed gains and geometric checks but with an inflexible elliptical equipotential.

Gravitational Lensing as an Optical Framework for Modified Gravity Theories
Gravitational lensing is recast as an optical phenomenon governed by effective refractive index, yielding closed-form deflection angles and Einstein radii for modified gravity models including deep-MOND, Yukawa, and p...
