Looking at the Fundamental Plane through a Gravitational Lens [PDF]
The Astrophysical Journal, 2006 We consider the Fundamental Plane of elliptical galaxies lensed by the gravitational field of a massive deflector (typically, a cluster of galaxies). We show that the Fundamental Plane relation provides a straightforward measurement of the projected mass distribution of the lens with a typical accuracy of ~0.15 in the dimensionless column density kappa.

Multimodal multi-output ordinal regression for discovering gravitationally-lensed transients
Machine Learning: Science and TechnologyGravitational lenses are caused by massive astronomical objects that distort space-time, bending light. They can distort transient astrophysical events, such as supernovae (SN), which are the subject of extensive study.

Detecting Dark Objects with Plasma Microlensing by Their Gravitational Wakes
The Astrophysical JournalA moving mass makes a gravitational wake in the partially ionized interstellar medium, which acts as a lens for radio-frequency light. Consequently, plasma microlensing could complement gravitational microlensing in the search for invisible massive ...

Auto-detection of strong gravitational lenses using convolutional neural networks
Emergent Scientist, 2018 We propose a method for the automated detection of strong galaxy-galaxy gravitational lenses in images, utilising a convolutional neural network (CNN) trained on 210 000 simulated galaxy-galaxy lens and non-lens images.

The quadrupole gravitational lens
The Astrophysical Journal, 1987 An asymmetric lens made of a spherically symmetric galaxy and a quadrupole tidal part allows a very simple pictorial examination of the multiplicity and positions of the images, for any mass density profile. The lens equations can be reduced to one equation in one variable.
