Detailed spectroscopy of decay products is one of the key technics in order to study nuclei far from stability. With the development of new radioactive ion beam facilities in Europe, very neutron-rich nuclei started to be available for such studies. As we go from the valley of stability towards the

The molecular gas phase in galaxies is an important tracer of the gas out of which stars are formed. However, observing this molecular gas is extremely difficult. Furthermore, state-of-the-art simulations provide different predictions for the amount of such gas in galaxies depending on the numerical

Recent advancements in astronomical observational programs have yielded unprecedented precision, yet they have not led to a convergence towards a singular cosmological model, notably the Lambda-Cold-Dark-Matter (?CDM) model. Instead of merely adjusting a handful of parameters or introducing new fiel

A new machine to study the internal structure of nucleons and nuclei will start operations in the early 2030s: the Electron-Ion Collider (EIC). The hardware contribution that this R&D project addresses (design of a large scale ASIC dedicated to AC-LGAD sensors) is ambitious and requires several ASIC

The CAVERNS project aims to boost the very first discovery of CP violation in the lepton sector at the current and incoming neutrino water Cherenkov detectors. CP violation in the lepton sector is the most promising way to explain the matter/antimatter asymmetry in our current universe through lep

Protons make up a large part of the visible Universe and yet our understanding of their structure is surprisingly limited. Although Quantum Chromodynamics (QCD) has the potential to explain their emergence in terms of quarks and gluons, it presents us with formidable challenges when it comes to extr

The next decade will witness one of the largest investment in history in neutrino fundamental physics with three leading flagship experiments: DUNE (USA), HyperKamiokande (Japan) and JUNO (China). Those experiments together will significantly enhance the world precision within the standard framework

Our project is aimed at the discovery and measurement of Primordial Magnetic Fields (PMFs) that are relics from the Big Bang. There exist several observational hints of the existence of such fields, such as evidence for non-zero magnetic fields in the voids of the Large Scale Structure in the prese

Understanding the properties and evolution of interstellar dust is a key to our knowledge of galaxy evolution. A promising way to progress in this field is to model the dust properties of galaxies at different stages of their evolution (i.e. at different metallicities). Contemporary dust models are

This proposal is intended to consolidate the French participation to the development of MOSAIC, the future multi-object fiber spectrograph for the European Southern Observatory (ESO) 39m Extremely Large Telescope (ELT). It is a first generation instrument, with unique capabilities in terms of multip

The FIRSTGAL project will combine ultra-deep observations from our accepted James Webb Space Telescope (JWST) large program GLIMPSE and state-of-the-art SPHINX simulations of galaxy formation to understand the feedback mechanisms that shape galaxies in the first billion years of the universe. Using

Nuclear g-factors are of the most accurate probes in modern nuclear physics investigations. Sensitive to the precise structure of the nuclear states, single-particle or collective nature is accessed directly by their measurement. At the border of nuclear existence, key regions of nuclei around 208Pb

How does a cloud of molecular gas and dust evolve to form a planetary system? What interstellar heritage does the latter retain? Does the chemical composition remain unchanged from molecular nebulae to emerging planets? Or does it reflect processes characteristic of the birth environment in which pl

The LHC and the new generation of gravitational detectors are providing a huge surge of experimental data, offering a unique opportunity to test the Standard Model of particle physics and Einstein's theory of gravity. To successfully implement this program, we need powerful methods for deriving high

Neutrinos are subatomic particles with unique properties that challenge the predictions of the Standard Model of particle physics. The discovery of neutrino flavor oscillations and, indirectly, of neutrino masses allows for the existence of a nuclear transition known as neutrinoless double beta deca

Studying cold planet demographics via microlensing and probing the nature of Dark Energy with Cosmic Shear and Baryonic Acoustic Oscillations, share the same requirements of a space-based infrared wide field imager. Microlensing has been listed as additional science of Euclid since 2007 following ou

Micro-Pattern Gaseous Detectors (MPGD) are largely used in particle physics experiments, thanks to their low material budget, remarkable performance and rather low cost for large-size detectors. The future experiments, and in particular the EPIC experiment on the future electron-ion collider EIC (BN

The Laser Interferometer Space Antenna (LISA) will explore the yet-uncharted millihertz band of the gravitational-wave (GW) spectrum in between the very low frequencies probed by pulsar timing arrays and the kilohertz window accessible to ground-based observatories. LISA's adoption is scheduled for

The DAMIC-M experiment at Modane uses a novel technology for direct dark matter (DM) detection. Using thick ultra low background charged coupled devices (CCDs) with an innovative skipper read-out it achieves a resolution of a fraction of an electron and lower the detection threshold to a few eV. Suc

Cosmology has made tremendous progress in the last twenty-five years in determining accurately the matter and energy content of the Universe. One of the major remaining questions is the generation of the density fluctuations that gave birth to the structures (galaxies, clusters of galaxies) that mak

The high-luminosity phase of the LHC (HL-LHC) starting in 2026, with the first data taking planned in Run 4 (2029-2032), will play a crucial role to provide some indications on the shortcomings of the Standard Model of particle physics. A precise, robust and fast particle track reconstruction is ess

The evolution of massive stellar binaries and the subsequent formation of binary neutron stars is an active field of research, powered by observations of Galactic binary pulsars as well as merging binary neutron stars that emit gravitational waves. The goal of this project is to explore the evolutio

This research project aims to develop advanced techniques for analyzing vast datasets from upcoming astronomical surveys, such as Euclid and LSST. These surveys aim to understand “Dark Energy”, the force behind the Universe’s accelerated expansion. They present specific challenges like handling ove

The direct detection of gravitational waves from merging binary systems marked a major breakthrough in physics. As we move toward the era of precision physics with gravitational waves with next-generation space and ground-based interferometers, one key observable will be the tidal deformability of t

This is a theoretical physics project focusing on the description, using the holographic duality, of the high density state of matter in strongly coupled gauge theories (such as the ones describing Neutron stars) and on the connection between theoretical description and observation via grav

ExaSKAle aims to model the reionisation epoch using cosmological simulations, at a time when the first JWST results are available and in preparation for the advent of SKA data. The project is based on the development and use of the new AMR code Dyablo, developed for hybrid and exascale architectures

With the CROSSWIND project we will aim to estimate the imprint of the dynamics of closed-field structures — that constitute most of the coronal volume in the solar atmosphere — in the young solar wind. We will in particular focus our effort on studying the interplay between the thermodynamics of t

Since the discovery of the Higgs boson at the CERN LHC, the hunt for new physics - new particles that are not predicted in the standard model (SM) of particle physics - has continued. In parallel, increasingly precise measurements of the Higgs boson and other SM particles are being performed. So far
