It is with extreme  sadness that we have just learned of the loss  of our colleague Cécile Renault, a talented astrophysicist at the laboratory of subatomic physics and cosmology in Grenoble. Cécile has been an active researcher in famous collaborations, like ARCHEOPS and PLANCK, and she is also known  for her involvement in the popularization of science. She ran her blog “COSMOLOGIQUEMENT VOTRE” (https://blogs.futura-sciences.com/renault/) with great passion and a strong commitment. Cecile was meant to attend the school. Our thoughts are with her family.

Description
This thematic school of CNRS aims to provide an overview of the most motivated current theories and tests of gravitation in different regimes, ranging from the scale of the solar system to that of the large structures of the Universe. The emphasis is on recent developments in connection with major current problems in cosmology, such as the origin of the acceleration of the expansion of the Universe. The topics covered are: gravitational waves, tests of gravity in the solar system, gravitation modified at very large scales and inhomogeneous cosmological models.
Main Topics
Gravitational Waves (Observational data, the strong field tests of GR, the perspectives of new Physics)
Tests in the solar system (Microscope and the equivalence principle, Ephemerides and new physics)
Modified gravity (cosmological tests, fundamental theories like massive gravity)
Inhomogeneous cosmology (Observational data, Theories)
Audience
The school is open to the international, it responds to a request from potential participants, such as CNRS researchers, academics and post-docs involved in this field. PhD students are also encouraged to attend: our future researchers.
Prerequisite
A doctoral level is required indifferently in Astronomy, Astrophysics, Theoretical Physics and Particle Physics. No preliminary upgrading is planned, but educational recommendations associated with the program will be passed on by speakers and will be posted on the school’s website.
Cette école thématique du CNRS a pour vocation de donner un panorama des théories actuelles les plus motivées et des tests de la gravitation dans les différents régimes, allant de l’échelle du système solaire à celle des grandes structures de l’Univers. L’accent est mis sur les développements récents en lien avec les grands problèmes actuels en cosmologie, comme par exemple l’origine de l’accélération de l’expansion de l’Univers. Les thèmes abordés sont : les ondes gravitationnelles, les tests de la gravitation dans le système solaire, la gravitation modifiée aux très grandes échelles et les modèles cosmologiques inhomogènes.
Grands Axes
Ondes Gravitationnelles (le point observationnel, les tests en champ fort de la RG, les perspectives de nouvelle physique)
Tests dans le système solaire (Microscope et le principe d’équivalence, Éphémérides et nouvelle physique)
Gravité modifiée (tests cosmologiques, théories fondamentales comme gravité massive)
Cosmologie inhomogène (le point observationnel, les théories)
Public concerné
L’école est ouverte à l’international, elle répond à une demande de la part des participants potentiels, tel que les chercheurs CNRS, universitaires et post-doctorants impliqués dans ce domaine. Sont encouragés à s’inscrire également les doctorants : nos futurs chercheurs.
Prérequis
Il est requis un niveau doctoral indifféremment en Astronomie, Astrophysique, Physique Théorique et Physique des particules. Il n’est pas prévu de mise à niveau préliminaire, mais des recommandations pédagogiques associées au programme seront transmises par les intervenants et figureront sur le site web de l’école.
