Weak Gravitational Lensing with COSMOS: Galaxy Selection and Shape Measurements
Weak Gravitational Lensing with COSMOS: Galaxy Selection and Shape Measurements
With a primary goal of conducting precision weak lensing measurements from space, the COSMOS survey has imaged the largest contiguous area observed by the Hubble Space Telescope (HST) to date using the Advanced Camera for Surveys (ACS). This is the first paper in a series where we describe our strategy …
