Emergent gravity in galaxies and in the Solar System
Aurelien Hees, Benoit Famaey, Gianfranco Bertone
It was recently proposed that the effects usually attributed to particle dark matter on galaxy scales are due to the displacement of dark energy by baryonic matter, a paradigm know…
Statistical Challenges in Fitting Stellar Orbits around the Supermassive Black Hole at the Galactic Center
Gregory Martinez, Kelly Kosmo, Aurelien Hees +2
Over two decades of astrometric and radial velocity data of short period stars in the Galactic center have the potential to provide unprecedented tests of General Relativity and in…
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…
