Fitting Gravitational Lenses: Truth or Delusion
Monthly Notices of the Royal Astronomical Society, no. 4 (2003): 1351-1364
EI WOS
摘要
The observables in a strong gravitational lens are usually just the image positions and sometimes the flux ratios. We develop a new and simple algorithm which allows a set of models to be fitted exactly to the observations. Taking our cue from the strong body of evidence that early-type galaxies are close to isothermal, we assume that the...更多
