Maximizing Kepler science return per telemetered pixel: Searching the habitable zones of the brightest stars
Benjamin T. Montet, Ruth Angus, Tom Barclay +9
In today's mailing, Hogg et al. propose image modeling techniques to maintain 10-ppm-level precision photometry in Kepler data with only two working reaction wheels. While these re…
Maximizing Kepler science return per telemetered pixel: Detailed models of the focal plane in the two-wheel era
David W. Hogg, Ruth Angus, Tom Barclay +9
Kepler's immense photometric precision to date was maintained through satellite stability and precise pointing. In this white paper, we argue that image modeling--fitting the Keple…
Sérsic galaxy models in weak lensing shape measurement: model bias, noise bias and their interaction
Tomasz Kacprzak, Sarah Bridle, Barnaby Rowe +4
Cosmic shear is a powerful probe of cosmological parameters, but its potential can be fully utilised only if galaxy shapes are measured with great accuracy. Two major effects have…
On a link between kernel mean maps and Fraunhofer diffraction, with an application to super-resolution beyond the diffraction limit
Stefan Harmeling, Michael Hirsch, Bernhard Schölkopf
We establish a link between Fourier optics and a recent construction from the machine learning community termed the kernel mean map. Using the Fraunhofer approximation, it identifi…
IM3SHAPE: A maximum-likelihood galaxy shear measurement code for cosmic gravitational lensing
Joe Zuntz, Tomasz Kacprzak, Lisa Voigt +3
We present and describe im3shape, a new publicly available galaxy shape measurement code for weak gravitational lensing shear. im3shape performs a maximum likelihood fit of a bulge…
