Thesis topic : Theories of Modified Gravity faced to future data of EUCLID survey
|
The study of the characteristics of dark energy, source of the acceleration of the expansion of the Universe, is currently at the center of the scientific concerns of many projects in Cosmology. The physical origin of this acceleration is in fact still totally unknown. The main index of acceleration of expansion is the Hubble diagram of type Ia supernovae. This thesis work is part of the study of some of these alternative models to general relativity in connection with the preparation of the scientific exploitation of the EUCLID mission.
-
One of the models to be studied initially is to try to account for current observations by assuming that the gravitational constant varies over time or with scale. Such a possibility fits for example in the context of cosmological models of "Brans-Dicke" type. In a second step, once a theory is well formulated and confronted with current data, the work will consist of examining the possible contribution of Euclid data to constrain an alternative model to the standard ΛCDM model.
-
The EUCLID satellite project is intended to better characterize the acceleration of the expansion of the Universe and its possible origin. The cosmological tests can be divided into two main categories: geometric tests that connect an observable to an intrinsic property of the object as is the case with the apparent luminosity of supernovae and the tests of measurement of the growth rate under the action of the gravitation of the initial density fluctuations. This second type of test has been implemented very little at present because it requires having large samples and good control of all the systematic. EUCLID will allow a much better level of statistics and systematic control on the weak lensing signal or the clustering properties of galaxies.
