Bayesian weak lensing tomography: Reconstructing the 3D large-scale distribution of matter with a lognormal prior
Vanessa Böhm, Stefan Hilbert, Maksim Greiner +1
We present a Bayesian reconstruction algorithm that infers the three-dimensional large-scale matter distribution from the weak gravitational lensing effects measured in the image s…
Cosmic expansion history from SNe Ia data via information field theory -- the charm code
Natàlia Porqueres, Torsten A. Enßlin, Maksim Greiner +4
We present charm (cosmic history agnostic reconstruction method), a novel inference algorithm that reconstructs the cosmic expansion history as encoded in the Hubble parameter $H(z…
Statistical methods for the analysis of rotation measure grids in large scale structures in the SKA era
Valentina Vacca, Niels Oppermann, Torsten Ensslin +18
To better understand the origin and properties of cosmological magnetic fields, a detailed knowledge of magnetic fields in the large-scale structure of the Universe (galaxy cluster…
All-sky reconstruction of the primordial scalar potential from WMAP temperature data
Sebastian Dorn, Maksim Greiner, Torsten A. Enßlin
An essential quantity required to understand the physics of the early Universe, in particular the inflationary epoch, is the primordial scalar potential and its statistics. We…
Log-transforming the matter power spectrum
Maksim Greiner, Torsten A. Enßlin
We investigate whether non-linear effects on the large-scale power spectrum of dark matter, namely the increase in small-scale power and the smearing of baryon acoustic oscillation…
