Accurate dark matter halo elongation from weak-lensing stacking analysis
Elizabeth J. Gonzalez, Kai Hoffmann, Enrique Gaztañaga +5
Shape estimates that quantify the halo anisotropic mass distribution are valuable parameters that provide information on their assembly process and evolution. Measurements of the m…
Linear and non-linear bias: predictions vs. measurements
Kai Hoffmann, Julien Bel, Enrique Gaztanaga
We study the linear and non-linear bias parameters which determine the mapping between the distributions of galaxies and the full matter density fields, comparing different measure…
Measuring the growth of matter fluctuations with third-order galaxy correlations
Kai Hoffmann, Julien Bel, Enrique Gaztanaga +3
Measurements of the linear growth factor at different redshifts are key to distinguish among cosmological models. One can estimate the derivative from red…
