Challenge.gov: Mapping Dark Matter

"The aim is to measure the shapes of galaxies to reconstruct the gravitational lensing signal in the presence ofnoise and a known Point Spread Function. The signal is a very small change in the galaxies'ellipticity, an exactly circular galaxy image would be changed into anellipse; however real galaxies are not circular. The challenge is to measure the ellipticity of 100,000 simulated galaxies."
