Detectors for both infinite physics

Detectors for both infinite physics

In the fields of instrumentation, Irfu's teams carry out the necessary instruments to see through its research in subatomic physics, astrophysics and cosmology. From the mechanical design of detectors to the realization and characterization of prototypes, and finally the integration and testing of final detectors, there are numerous expertises such as microstructured gas detectors, imagers and space spectro-imagers in different wavelengths (gammas, X, visible, infrared and submillimetre waves).

Evolution of the large structures and galaxies

Today our Universe is made up of stars, galaxies, clusters of galaxies but also huge voids. Yet when it was born over 13 billion years ago, matter was evenly distributed. To understand the physical mechanisms responsible for this scenario, we need to trace the history of galaxies and their clustering by combining the three pillars which are observations, theoretical data modelling and numerical simulations.

Galaxy formation and evolution

Galaxy formation and evolution

Observational Cosmology has reached an important turning point. After years of seeking the parameters that govern the evolution of the Universe, there seems to be increasing consensus in acknowledging the dominant influence of dark matter on baryons and that of dark energy on dark matter.

Planets, star's formation and dynamics, interstellar medium

We are studying how stars work, the Sun first of all. We have deepened our knowledge of the Sun via helioseismology observations (discovery of global gravity modes with SOHO-GOLF (Garcia et al., Science 316, 1591 (2007)) and large magneto-hydrodynamics simulations on massively parallel computers (Brun et al. ApJ, 742, 79).

Dark Universe

Dark Universe

The most intriguing development in modern cosmology is to realise that the better part of the Universe is essentially of unknown nature.  This conclusion relies on two types of observations.  The first one is the indirect evidence since decades of the presence of a large quantity of invisible matter, called dark matter, whose gravitational influence spans all cosmic scales, from galaxy to clusters of galaxies, and the whole Universe.

High energy cosmic phenomena and astroparticles

At high energies, the violent phenomena of the Universe are linked to the production of radiation and particles such as X-rays, gamma rays, subatomic particles of all types (charged particles, neutrinos, etc.) and to the extreme th gravitational radiation. The aim of studying this radiation is to understand what mechanisms are capable of producing the acceleration of galactic and extragalactic particles within compact objects and their environment.
