New tests of local Lorentz invariance and local position invariance of gravity with pulsars
Lijing Shao, Norbert Wex, Michael Kramer
New tests are proposed to constrain possible deviations from local Lorentz invariance and local position invariance in the gravity sector. By using precise timing results of two bi…
New Constraints on Preferred Frame Effects from Binary Pulsars
Lijing Shao, Norbert Wex, Michael Kramer
Preferred frame effects (PFEs) are predicted by a number of alternative gravity theories which include vector or additional tensor fields, besides the canonical metric tensor. In t…
Tests of the universality of free fall for strongly self-gravitating bodies with radio pulsars
Paulo C. C. Freire, Michael Kramer, Norbert Wex
In this paper, we review tests of the strong equivalence principle (SEP) derived from pulsar-white dwarf data. The extreme difference in binding energy between both components and…
