An improved map of the Galactic Faraday sky
N. Oppermann, H. Junklewitz, G. Robbers +28
We aim to summarize the current state of knowledge regarding Galactic Faraday rotation in an all-sky map of the Galactic Faraday depth. For this we have assembled the most extensiv…
Improving stochastic estimates with inference methods: calculating matrix diagonals
Marco Selig, Niels Oppermann, Torsten A. Enßlin
Estimating the diagonal entries of a matrix, that is not directly accessible but only available as a linear operator in the form of a computer routine, is a common necessity in man…
Reconstructing signals from noisy data with unknown signal and noise covariance
Niels Oppermann, Georg Robbers, Torsten A. Ensslin
We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences.…
