KiDS+VIKING+GAMA: Halo occupation distributions and correlations of satellite numbers with a new halo model of the galaxy-matter bispectrum for galaxy-galaxy-galaxy lensing
Laila Linke, Patrick Simon, Peter Schneider +3
Halo models and halo occupation distributions (HODs) are important tools to model the galaxy and matter distribution. We present and assess a new method for constraining the parame…
Exact law for compressible pressure-anisotropic magnetohydrodynamic turbulence: toward linking energy cascade and instabilities
P. Simon, F. Sahraoui
We derive a first exact law for compressible pressure-anisotropic magnetohydrodynamic turbulence. For a gyrotropic pressure tensor, we study the double-adiabatic case and show the…
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…
KiDS+VIKING+GAMA: Testing semi-analytic models of galaxy evolution with galaxy-galaxy-galaxy lensing
Laila Linke, Patrick Simon, Peter Schneider +9
Several semi-analytic models (SAMs) try to explain how galaxies form, evolve and interact inside the dark matter large-scale structure. These SAMs can be tested by comparing their…
Minimising the impact of scale-dependent galaxy bias on the joint cosmological analysis of large scale structures
Marika Asgari, Indiarose Friswell, Mijin Yoon +5
We present a mitigation strategy to reduce the impact of non-linear galaxy bias on the joint `pt' cosmological analysis of weak lensing and galaxy surveys. The -sta…
The importance of magnification effects in galaxy-galaxy lensing
Sandra Unruh, Peter Schneider, Stefan Hilbert +3
Magnification changes the observed number counts of galaxies on the sky. This biases the observed tangential shear profiles around galaxies, the so-called galaxy-galaxy lensing (GG…
