Probing primordial non-Gaussianity with Fast Radio Bursts
Robert Reischke, Steffen Hagstotz, Robert Lilow
Fast radio bursts (FRBs) are astrophysical transients of currently unknown origin, and so far several events have been detected at extragalactic distances. The dispersion measure (…
Information entropy in cosmological inference problems
Ana Marta Pinho, Robert Reischke, Marie Teich +1
The subject of this paper is a quantification of the information content of cosmological probes of the large-scale structures, specifically of temperature and polarisation anisotro…
Information geometry in cosmological inference problems
Eileen Giesel, Robert Reischke, Björn Malte Schäfer +1
Statistical inference more often than not involves models which are non-linear in the parameters thus leading to non-Gaussian posteriors. Many computational and analytical tools ex…
Post-inflationary axion isocurvature perturbations facing CMB and large-scale structure
Martin Feix, Steffen Hagstotz, Andreas Pargner +3
Dark matter comprised of axion-like particles (ALPs) generated by the realignment mechanism in the post-inflationary scenario leads to primordial isocurvature fluctuations. The pow…
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…
