Full-sky bispectrum in redshift space for 21cm intensity maps
Ruth Durrer, Mona Jalilvand, Rahul Kothari +2
We compute the tree-level bispectrum of 21cm intensity mapping after reionisation. We work in the directly observable angular and redshift space, focusing on equal-redshift correla…
The Flat Sky Approximation to Galaxy Number Counts
William L. Matthewson, Ruth Durrer
We derive and test an approximation for the angular power spectrum of galaxy number counts in the flat sky limit. The standard density and redshift space distortion (RSD) terms in…
Primordial magnetic helicity evolution with a homogeneous magnetic field from inflation
Axel Brandenburg, Ruth Durrer, Yiwen Huang +3
Motivated by a scenario of magnetogenesis in which a homogeneous magnetic field is generated during inflation, we study the magnetohydrodynamic evolution of the primordial plasma m…
On the importance of lensing for galaxy clustering in photometric and spectroscopic surveys
Goran Jelic-Cizmek, Francesca Lepori, Camille Bonvin +1
We study the importance of gravitational lensing in the modelling of the number counts of galaxies. We confirm previous results for photometric surveys, showing that lensing cannot…
Weak-lensing observables in relativistic N-body simulations
Francesca Lepori, Julian Adamek, Ruth Durrer +2
We present a numerical weak-lensing analysis that is fully relativistic and non-perturbative for the scalar part of the gravitational potential and first-order in the vector part,…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
