Improving parametric mass modelling of lensing clusters through a perturbative approach
Benjamin Beauchesne, Benjamin Clément, Johan Richard +2
We present a new method to model the mass distribution of galaxy clusters that combines a parametric and a free-form approach to reconstruct cluster cores with strong lensing const…

An Atlas of MUSE Observations towards Twelve Massive Lensing Clusters
Johan Richard, Adélaïde Claeyssens, David J. Lagattuta +25
Spectroscopic surveys of massive galaxy clusters reveal the properties of faint background galaxies, thanks to the magnification provided by strong gravitational lensing. We presen…
