Résumé |
High-precision astrometric experiments will allow to detect our proper acceleration through
space via real-time observations of the change in the aberration of sources at cosmic
distances. This Aberration Drift effect is a powerful consistency test of FLRW metrics, it may
set independent constraints on the amplitude of the Hubble constant and the linear growth rate
of cosmic structures, and it may also be instrumental in searching for evidences of new physics
beyond the standard model. I will present the mechanics of this novel test of cosmology,
discuss the physics to which it is sensitive and show simulated forecasts of the accuracy with
which it can be implemented by ongoing satellite missions such as Gaia or upgraded future
experiments. |
