Gap interpolation by inpainting methods : Application to Ground and Space-based Asteroseismic data
Sandrine Pires, Savita Mathur, Rafael A. Garcia +3
In asteroseismology, the observed time series often suffers from incomplete time coverage due to gaps. The presence of periodic gaps may generate spurious peaks in the power spectr…
Impact on asteroseismic analyses of regular gaps in Kepler data
R. A. Garcıa, S. Mathur, S. Pires +11
The NASA Kepler mission has observed more than 190,000 stars in the constellations of Cygnus and Lyra. Around 4 years of almost continuous ultra high-precision photometry have been…
A PCA-based automated finder for galaxy-scale strong lenses
R. Joseph, F. Courbin, R. B. Metcalf +11
We present an algorithm using Principal Component Analysis (PCA) to subtract galaxies from imaging data, and also two algorithms to find strong, galaxy-scale gravitational lenses i…
Weak Lensing Galaxy Cluster Field Reconstruction
Eric Jullo, Sandrine Pires, Mathilde Jauzac +1
In this paper, we compare three methods to reconstruct galaxy cluster density fields with weak lensing data. The first method called FLens integrates an inpainting concept to inver…
Sparsely Sampling the Sky: Regular vs Random Sampling
P. Paykari, S. Pires, J. -L. Starck +1
The next generation of galaxy surveys, aiming to observe millions of galaxies, are expensive both in time and cost. This raises questions regarding the optimal investment of this t…
Origins of weak lensing systematics, and requirements on future instrumentation (or knowledge of instrumentation)
Richard Massey, Henk Hoekstra, Thomas Kitching +11
The first half of this paper explores the origin of systematic biases in the measurement of weak gravitational lensing. Compared to previous work, we expand the investigation of PS…
