CCCP and MENeaCS: (updated) weak-lensing masses for 100 galaxy clusters
Ricardo Herbonnet, Cristóbal Sifón, Henk Hoekstra +7
Large area surveys have detected significant samples of galaxy clusters that can be used to constrain cosmological parameters, provided that the masses of the clusters are measured…
The impact of the observed baryon distribution in haloes on the total matter power spectrum
Stijn N. B. Debackere, Joop Schaye, Henk Hoekstra
The interpretation of upcoming weak gravitational lensing surveys depends critically on our understanding of the matter power spectrum on scales , where bary…
KiDS+VIKING-450 and DES-Y1 combined: Cosmology with cosmic shear
S. Joudaki, H. Hildebrandt, D. Traykova +12
We present a combined tomographic weak gravitational lensing analysis of the Kilo Degree Survey (KV450) and the Dark Energy Survey (DES-Y1). We homogenize the analysis of these two…
GAMA+KiDS: Alignment of galaxies in galaxy groups and its dependence on galaxy scale
Christos Georgiou, Nora Elisa Chisari, Maria Cristina Fortuna +11
Intrinsic galaxy alignments are a source of bias for weak lensing measurements as well as a tool for understanding galaxy formation and evolution. In this work, we measure the alig…
Propagating Residual Biases in Cosmic Shear Power Spectra
T. D. Kitching, P. Paykari, H. Hoekstra +1
In this paper we derive a full expression for the propagation of multiplicative and additive shape measurement biases into the cosmic shear power spectrum. In doing so we identify…
The case for two-dimensional galaxy-galaxy lensing
Andrej Dvornik, Sebastiaan L. Zoutendijk, Henk Hoekstra +1
We revisit the performance and biases of the two-dimensional approach to galaxy-galaxy lensing. This method exploits the information for the actual positions and ellipticities of s…
