They used techniques, some new, some over a century old, which take measurement noise into account. (sciencedaily.com)
Instead, the authors argue, these conclusions result from interpreting measurement noise as biology. (sciencedaily.com)
Taking models of galaxies from the Hubble Space Telescope Ultra Deep Field (HUDF) and applying a correction for the HUDF point spread function we generate lensed simulations of deep, opti... ▽ More We present a simulation analysis of weak gravitational lensing flexion and shear measurement using shapelet decomposition, and identify differences between flexion and shear measurement noise in deep survey data.
