Realistic systematic biases induced by residual intrinsic alignments in cosmic shear surveys
Robert Reischke, Björn Malte Schäfer
We study the parameter estimation bias induced by intrinsic alignments on a Euclid-like weak lensing survey. For the intrinsic alignment signal we assume a composite alignment mode…
The Probability Distribution of Astrophysical Gravitational-Wave Background Fluctuations
Yonadav Barry Ginat, Vincent Desjacques, Robert Reischke +1
The coalescence of compact binary stars is expected to produce a stochastic background of gravitational waves (GW) observable with future GW detectors. Such backgrounds are usually…
The information content of Cosmic Infrared Background anisotropies
Robert Reischke, Vincent Desjacques, Saleem Zaroubi
We use analytic computations to predict the power spectrum as well as the bispectrum of Cosmic Infrared Background (CIB) anisotropies. Our approach is based on the halo model and t…
Isocurvature bounds on axion-like particle dark matter in the post-inflationary scenario
Martin Feix, Johann Frank, Andreas Pargner +3
We assume that dark matter is comprised of axion-like particles (ALPs) generated by the realignment mechanism in the post-inflationary scenario. This leads to isocurvature fluctuat…
KiDS+GAMA: Constraints on Horndeski gravity from combined large-scale structure probes
Alessio Spurio Mancini, Fabian Köhlinger, Benjamin Joachimi +7
We present constraints on Horndeski gravity from a combined analysis of cosmic shear, galaxy-galaxy lensing and galaxy clustering from of the Kilo-Degree Surv…
