The local dust foregrounds in the microwave sky: I. Thermal emission spectra
V. Dikarev, O. Preuss, S. Solanki +2
Analyses of the cosmic microwave background (CMB) radiation maps made by the Wilkinson Microwave Anisotropy Probe (WMAP) have revealed anomalies not predicted by the standard infla…
Is the physics within the Solar system really understood?
C. Lämmerzahl, O. Preuss, H. Dittus
A collection is made of presently unexplained phenomena within our Solar system and in the universe. These phenomena are (i) the Pioneer anomaly, (ii) the flyby anomaly, (iii) the…
Gravity-induced birefringence within the framework of Poincare gauge theory
Oliver Preuss, Sami K. Solanki, M. P. Haugan +1
Gauge theories of gravity provide an elegant and promising extension of general relativity. In this paper we show that the Poincaré gauge theory exhibits gravity-induced birefringe…
Constraining Gravitational Theories by Observing Magnetic White Dwarfs
Oliver Preuss, Stefan Jordan, Mark P. Haugan +1
Under the assumption of a specific nonminimal coupling of torsion to Under the assumption of a specific nonminimal coupling of torsion to electromagnetism, spacetime is birefringen…
An astronomical search for evidence of new physics: Limits on gravity-induced birefringence from the magnetic white dwarf RE J0317-853
Oliver Preuss, Mark P. Haugan, Sami K. Solanki +1
The coupling of the electromagnetic field directly with gravitational gauge fields leads to new physical effects that can be tested using astronomical data. Here we consider a part…
Astronomical Tests of the Einstein Equivalence Principle
Oliver Preuss
The Einstein equivalence principle is certainly a key element in the development of new enhanced theories of gravity. Although being an important building block in Einstein's gener…
