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…

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.…

Phenomenology of Gravitational Aether as a solution to the Old Cosmological Constant Problem

Siavash Aslanbeigi, Georg Robbers, Brendan Z. Foster +2

One of the deepest and most long-standing mysteries in physics has been the huge discrepancy between the observed vacuum density and our expectations from theories of high energy p…

Planck Early Results. V. The Low Frequency Instrument data processing

A. Zacchei, D. Maino, C. Baccigalupi +146

We describe the processing of data from the Low Frequency Instrument (LFI) used in production of the Planck Early Release Compact Source Catalogue (ERCSC). In particular, we discus…

Probing magnetic helicity with synchrotron radiation and Faraday rotation

N. Oppermann, H. Junklewitz, G. Robbers +1

We present a first application of the recently proposed LITMUS test for magnetic helicity, as well as a thorough study of its applicability under different circumstances. In order…

Reconstructing the evolution of dark energy with variations of fundamental parameters

N. J. Nunes, T. Dent, C. J. A. P. Martins +1

Under the assumption that the variations of parameters of nature and the current acceleration of the universe are related and governed by the evolution of a single scalar field, we…
