Range, Doppler and astrometric observables computed from Time Transfer Functions: a survey
A. Hees, S. Bertone, C. Le Poncin-Lafitte +1
Determining range, Doppler and astrometric observables is of crucial interest for modelling and analyzing space observations. We recall how these observables can be computed when t…
Observables in theories with a varying fine structure constant
A. Hees, O. Minazzoli, J. Larena
We show how two seemingly different theories with a scalar multiplicative coupling to electrodynamics are actually two equivalent parametrisations of the same theory: despite some…
Light propagation in the field of a moving axisymmetric body: theory and application to JUNO
A. Hees, S. Bertone, C. Le Poncin-Lafitte
Given the extreme accuracy of modern space science, a precise relativistic modeling of observations is required. We use the Time Transfer Functions formalism to study light propaga…
Breaking of the equivalence principle in the electromagnetic sector and its cosmological signatures
A. Hees, O. Minazzoli, J. Larena
This paper proposes a systematic study of cosmological signatures of modifications of gravity via the presence of a scalar field with a multiplicative coupling to the electromagnet…
Late-time cosmology of scalar-tensor theories with universal multiplicative coupling between the scalar field and the matter Lagrangian
Olivier Minazzoli, Aurélien Hees
We investigate the late-time cosmological behaviour of scalar-tensor theories with a universal multiplicative coupling between the scalar field and the matter Lagrangian in the mat…
Tests of Gravitation at Solar System scales beyond the PPN formalism
A. Hees, W. M. Folkner, R. A. Jacobson +4
In this communication, the current tests of gravitation available at Solar System scales are recalled. These tests rely mainly on two frameworks: the PPN framework and the search f…
