Grille de Recherche de l'Ile de France
Présentation générale:
Objectifs - contexte:
Le projet de grille de calcul au service de la recherche d’Ile de France GRIF a pour objectif la mise en place d’une grille de calcul fédérant les grands centres de recherche de la région parisienne autour d’un outil commun dans le cadre de la grille européenne EGEE et de la grille mondiale LCG.

ESA space telescope for extra solar planets infrared observation.
Physics case
The overall picture of particle physics, the so-called Standard Model, has been recently probed by the discovery at CERN of the Higgs particle; it is consistent with the existence of three neutrinos. Oscillations between these neutrinos has been observed in many experiments and are already a compelling evidence of new physics beyond the Standard Model.

The Herschel Dwarf Galaxy Survey
"The ISM in Low Metallicity Environments: Bridging the Gap Between Local Universe and Primordial Galaxies"
The Herschel Dwarf Galaxy Survey is a Guaranteed Time Key Program led by Suzanne Madden.
Evidence for large-scale excesses associated with low HI column densities in the sky
Where dust and gas are uniformly mixed, atomic hydrogen can be traced through the detection of far-infrared or UV emission of dust.
We considered, for the origin of discrepancies observed between various direct and indirect tracers of gas outside the Galactic plane, possible corrections to the zero levels of the Planck-HFI detectors.
Hadron electromagnetic form factors parametrize the internal structure of hadrons, the dynamical distribution of magnetization and charge created by the inner constituents.
They are considered fundamental quantities as they are a privileged background for interplay between theory and experiment.
The calibrated GOLF (Global Oscillations at Low Frequencies) /SoHO space observations and several derived data products are available below. They are regularly updated (last update December 2017).

La nature de ces nouvelles fonctions
Des progrès théoriques importants survenus dans les cinq dernières années permettent d'étendre considérablement la notion de distributions de partons dans un nucléon ou un méson.
Taking into account the professions of scientific research, technological instrument development, project management and its value-creating activities, Irfu has created an active network of Irfu alumni based on common values such as solidarity and contributing to Irfu's influence.
This network makes it possible in particular to set up and implement training actions and exchange actions between alumni and current students/CDs in order to help them in their professional integration.
Thèmes-programmes:
Thématique et contexte du projet In parallel with the experimental activities of the MNM group at DAPNIA/SPhN some fundamental and applied modelling takes place to simulate innovative nuclear systems for nuclear waste transmutation, intensive neutron sources based on spallation and photonuclear reactions, radioactive nuclear beam production scenarios, dismantling of nuclear installations, etc.
Spectroscopy and Identification of Rare Isotopes Using S3
The high-intensity stable beams of the superconducting linear accelerator of the SPIRAL2 facility at GANIL coupled with the Super Separator Spectrometer (S3) and a high-performance focal-plane spectrometer will open new horizons for the research in the domains of rare nuclei and low cross-section phenomena at the limit of nuclear stability.

Measurement of the active neutrino mass scale and search for light sterile neutrinos
The KATRIN experiment
Neutrinos are the most abundant matter particles of the Universe, but also the lightest! In 2015 the Nobel prize was awarded for the discovery of neutrino oscillations, which shows that neutrinos have mass. Their tiny mass is a compelling evidence for physics beyond the standard model of elementary particle physics.

Variability of solar IRradiance and Gravity Oscillations / Sun PhotoMeters
The scientific objective of the VIRGO experiment (Variability of solar IRradiance and Gravity Oscillations) on board SOHO (Solar and Heliospheric Observatory) is to determine the characteristics of pressure and internal gravity oscillations by observing irradiance and radiance variations, to measure the solar total and spectral irradiance, and to quantify their variability over periods of days to the duration of the mission. With these data helioseismological methods can be used to probe the solar interior.
