“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.”
Aussie student finds universe’s ‘missing mass’, AFP
“A 22-year-old Australian university student has solved a problem which has puzzled astrophysicists for decades, discovering part of the so-called “missing mass” of the universe during her summer break. Undergraduate Amelia Fraser-McKelvie made the breakthrough during a holiday internship with a team at Monash University’s School of Physics, locating the mystery material within vast structures called “filaments of galaxies”.
