High Performance Computing for gravitational lens modeling: single vs double precision on GPUs and CPUs
Markus Rexroth, Christoph Schäfer, Gilles Fourestey +1
Strong gravitational lensing is a powerful probe of cosmology and the dark matter distribution. Efficient lensing software is already a necessity to fully use its potential and the…
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…
A new method to break the mass sheet degeneracy using aperture moments
Markus Rexroth, Priyamvada Natarajan, Jean-Paul Kneib
Mass determinations from gravitational lensing shear and the higher order estimator flexion are both subject to the mass sheet degeneracy. Mass sheet degeneracy refers to a transfo…
