Gravitational Microlensing - Extreme Microlensing Events

Extreme Microlensing Events

In a typical microlensing event, the light curve is well fit by assuming that the source is a point, the lens is a single point mass, and the lens is moving in a straight line: the point source-point lens approximation. In these events, the only physically significant parameter that can be measured is the Einstein timescale . However, in some cases, events can be analyzed to yield the additional parameters of the Einstein angle and parallax: and . These include very high magnification events, binary lenses, parallax, and xallarap events, and events where the lens is visible.

Famous quotes containing the words extreme and/or events:

    Art knows no happier moment than the opportunity to show the symmetry of an extreme, during that moment of spheric harmony when the dissonance dissolves for the blink of an eye, dissolves into a blissful harmony, when the most extreme opposites, coming together from the greatest alienation, fleetingly touch with lips of the word and of love.
    Stefan Zweig (18811942)

    The prime lesson the social sciences can learn from the natural sciences is just this: that it is necessary to press on to find the positive conditions under which desired events take place, and that these can be just as scientifically investigated as can instances of negative correlation. This problem is beyond relativity.
    Ruth Benedict (1887–1948)
