Abstract: (Abridged) We examine the effects of charge transfer inefficiency (CTI) during CCD readout on galaxy shape measurements required by studies of weak gravitational lensing. (arxiv.org)
We predict that for galaxies furthest from the readout registers, bias in the measurement of galaxy shapes, Delta (e), will increase at a rate of 2.65 + / - 0.02 x 10 ^ -LRB--4) per year at L2 for accumulated radiation exposure averaged over the solar cycle. (arxiv.org)
She found the blob as she was classifying galaxy shapes from astronomical images as part of the online Galaxy Zoo project, which aims to harness the power of volunteers to answer cosmological questions. (newscientist.com)
