AMICO galaxy clusters in KiDS-DR3: the impact of estimator statistics on the luminosity-mass scaling relation
Merijn Smit, Andrej Dvornik, Mario Radovich +4
As modern-day precision cosmology aims for statistical uncertainties of the percent level or lower, it becomes increasingly important to reconsider estimator assumptions at each st…

Chasing the peak: optimal statistics for weak shear analyses
Merijn Smit, Konrad Kuijken
Weak gravitational lensing analyses are fundamentally limited by the intrinsic, non-Gaussian distribution of galaxy shapes. We explore alternative statistics for samples of ellipti…

The mass distribution in an assembling super galaxy group at
Merijn Smit, Tim Schrabback, Malin Velander +4
We present a weak gravitational lensing analysis of supergroup SG11201202, consisting of four distinct X-ray-luminous groups, that will merge to form a cluster comparable in mas…
