Weak lensing mass modeling bias and the impact of miscentring

Martin W. Sommer, Tim Schrabback, Douglas E. Applegate +4

Parametric modeling of galaxy cluster density profiles from weak lensing observations leads to a mass bias, whose detailed understanding is critical in deriving accurate mass-obser…

CFHTLenS: Galaxy bias as function of scale, stellar mass, and colour. Conflicts with predictions by semi-analytic models

Patrick Simon, Stefan Hilbert

Galaxy models predict a tight relation between the clustering of galaxies and dark matter on cosmological scales, but predictions differ notably in the details. We used this opport…

Mass calibration of distant SPT galaxy clusters through expanded weak lensing follow-up observations with HST, VLT & Gemini-South

T. Schrabback, S. Bocquet, M. Sommer +18

Expanding from previous work we present weak lensing measurements for a total sample of 30 distant () massive galaxy clusters from the South Pole Telescope…

Joint galaxy-galaxy lensing and clustering constraints on galaxy formation

Malin Renneby, Bruno M. B. Henriques, Stefan Hilbert +5

We compare predictions for galaxy-galaxy lensing profiles and clustering from the Henriques et al. (2015) public version of the Munich semi-analytical model of galaxy formation (SA…

Fast estimation of aperture-mass statistics I: aperture mass variance and an application to the CFHTLenS data

Lucas Porth, Robert E. Smith, Patrick Simon +2

We explore an alternative method to the usual shear correlation function approach for the estimation of aperture mass statistics in weak lensing survey data. Our approach builds on…

Time Delay Lens Modelling Challenge

X. Ding, T. Treu, S. Birrer +26

In recent years, breakthroughs in methods and data have enabled gravitational time delays to emerge as a very powerful tool to measure the Hubble constant . However, published…
