Particles physics, Astrophysics, Geosciences, Environment and ecology (PAGE)
This research pole covers the fields of particle and nucleus Physics, Astrophysics, the Earth, the Environment and ecology. This work contributes to the development and exploitation of large instruments, long-term observation means and research infrastructures, in the framework of a national and international programs. It relies on important and innovative instrumental developments and numerical means (calculations, data), and addresses several major societal challenges.
Strategic axes
The universe: origin, composition, evolution
Research of new physics at the Large Hadron Collider (LHC): origin of masses, new particles, matter-antimatter asymmetry, properties of the plasma of quarks and gluons.
Neutrino physics: measuring charge-parity symmetry violation, in connection with the origin of matter-antimatter asymmetry.
Nature of dark matter and dark energy in the Universe, combining ground-based and space-based observations of astro-particles and massive structures such as galaxy clusters.
Multi-messenger astrophysics: characterize the sources of gravitational waves, and more generally the sky at high energies (cosmic rays, gamma rays).
Stellar systems, planetary systems & planet Earth
Interstellar medium and star formation: dependence of star properties on the structure, dynamics, magnetic field, and chemistry of the interstellar medium.
Proto-planetary disks: understanding the formation of planets and the role of the magnetic field in the coupling of the disk with its star.
Extra-solar planets: detection, characterization (core, atmosphere) and dynamics to understand their diversity and origin.
Solar system: exobiology via missions to study the moons of Jupiter and Saturn, and the return of Martian samples to Earth.
Planetary cores, in particular that of the Earth: simulations of the dynamics of the Earth's core, with the contribution of applied mathematics and satellite data assimilation algorithms.
Earth and anthropization: climate, ecosystems, risks, resources
Climate-water: regionalization of climate models to understand the effects of global change on hydrological regimes in mountain environments, on ice caps, and in intertropical zones.
Anthropocene: understanding the coupled themes of climate - human activities - environmental quality, including analytical studies, contaminant dynamics, and characterization of extreme events.
Biodiversity and ecosystems: evolution and spatial variations, respective contributions of climate, soil and pollutants.
Physics, Chemistry and dynamics of the Earth: at all time and space scales.
Geo-resources: identification, modalities of formation and variability, exploitation and recycling.
Natural risks and hazards: multidisciplinary approaches to natural hazards and risk for the purpose of anticipating future risks in the context of global change.
