Statistics of a single sky: constrained random fields and the imprint of Bardeen potentials on galaxy clustering
Vincent Desjacques, Yonadav Barry Ginat, Robert Reischke
We explore the implications of a single observer's viewpoint on measurements of galaxy clustering statistics. We focus on the Bardeen potentials, which imprint characteristic scale…
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…
Optimising tomography for weak gravitational lensing surveys
Marvin Sipp, Bjoern Malte Schaefer, Robert Reischke
The subject of this paper is optimisation of weak lensing tomography: We carry out numerical minimisation of a measure of total statistical error as a function of the redshifts of…
