Simple Models for the Distribution of Dark Matter
Jin H. An, N. Wyn Evans
We introduce a simple family of models for representing the dark matter in galaxies. The potential and phase space distribution function are all elementary, while the density is cu…
Gravitational lens under perturbations: Symmetry of perturbing potentials with invariant caustics
Jin H. An
When the gravitational lensing potential can be approximated by that of circularly symmetric system affected by weak perturbations, it is found that the shape of the resulting (tan…
Effect of a wide binary companion to the lens on the astrometric behavior of gravitational microlensing events
Jin H. An, Cheongho Han
In this paper, we investigate the effect of a wide binary companion of the lens on the astrometric behavior of Galactic gravitational microlensing events and compare it to the effe…
Microlensing Constraints on the Frequency of Jupiter Mass Planets
B. Scott Gaudi, M. D. Albrow, Jin H. An +17
Microlensing is the only technique likely, within the next 5 years, to constrain the frequency of Jupiter-analogs. The PLANET collaboration has monitored nearly 100 microlensing ev…
