Addendum to Astro-ph/0207612: Reflection Symmetry of Cusps in Gravitational Lensing

Sun Hong Rhie

A contour plot of positive iso-J curves is shown for a gravitational binary lens epsilon_2 = 0.1883 and ell = 0.687. The caustic curve is made of 4-cusped central caustic (so-calle…

Reflection Symmetry of Cusps in Gravitational Lensing

Sun Hong Rhie

Criticality in graviational microlensing is an everyday issue because that is what generates microlensing signals which may be of photon-challenged compact objects such as black ho…

The Microlensing Event MACHO-99-BLG-22/OGLE-1999-BUL-32: An Intermediate Mass Black Hole, or a Lens in the Bulge

D. P. Bennett, A. C. Becker, J. J. Calitz +5

We present an re-analysis of the longest timescale gravitational microlensing event discovered to date: MACHO-99-BLG-22/OGLE-1999-BUL-32, which was discovered by both the MACHO and…

Line Caustic Revisted: Which distance is in ?

Sun Hong Rhie

The line caustic behavior has been discussed since Chang and Refsdal (1979) mentioned inverse-square-root-of-the-distance dependence of the amplification of the images near the cri…

How Cumbersome is a Tenth Order Polynomial?: The Case of Gravitational Triple Lens Equation

Sun Hong Rhie

Three point mass gravitational lens equation is a two-dimensional vector equation that can be embedded in a tenth order analytic polynomial equation of one complex variable, and we…
