Sparse Lens Inversion Technique (SLIT): lens and source separability from linear inversion of the source reconstruction problem
R. Joseph, F. Courbin, J. -L. Starck +1
Strong gravitational lensing offers a wealth of astrophysical information on the background source it affects, provided the lensed source can be reconstructed as if it was seen in…
IFS-RedEx, a redshift extraction software for integral-field spectrographs: Application to MUSE data
Markus Rexroth, Jean-Paul Kneib, Rémy Joseph +2
We present IFS-RedEx, a spectrum and redshift extraction pipeline for integral-field spectrographs. A key feature of the tool is a wavelet-based spectrum cleaner. It identifies rel…
Multi-band morpho-Spectral Component Analysis Deblending Tool (MuSCADeT): Deblending colourful objects
R. Joseph, F. Courbin, J. -L. Starck
We introduce a new algorithm for colour separation and deblending of multi-band astronomical images called MuSCADeT which is based on Morpho-spectral Component Analysis of multi-ba…
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…
