Constructing Exact Confidence Regions on Parameter Manifolds of Non-Linear Models
Rafael Arutjunjan, Bjoern Malte Schaefer, Clemens Kreutz
Using the mathematical framework of information geometry, we introduce a novel method which allows one to efficiently determine the exact shape of simultaneous confidence regions f…

Three-dimensional weak gravitational lensing of the 21-cm radiation background
Jose Agustin Lozano Torres, Bjoern Malte Schaefer
We study weak gravitational lensing by the cosmic large-scale structure of the 21-cm radiation background in the 3d-weak lensing formalism. The interplay between source distance me…
