Processing of Polychromatic Interferometric Data for Astrophysics – POLCA
By combining the light from several telescopes, Optical Interferometry (OI) provides the highest angular resolution (milliarcsecond resolution) in many fields such as stellar physics, star and planet formation, and environment of extra galactic black holes. In this field, the pioneering work in Fran

Dissecting the past and present mechanisms of the inner Milky Way – GALHIS
With the up-coming of large scale spectroscopic surveys, the analysis of the spatial distributions of chemical abundances on the one hand, and of stellar velocities of the other hand, brings new constraints for our understanding of Galactic evolution. Combining observational approaches, collecting w

VIRAGE: Virgo - Alterations of Galaxies within dense Environments – VIRAGE
VIRAGE is a program that aims to understand whether the dominant processes of galaxy transformations are internal to galaxies (nature) or due to their interactions with the environment (nurture). We address this question by a detailed characterization of environmental effects within the densest envi
On the origin of exozodiacal dust – EXOZODI
The EXOZODI ANR project allowed us to address the issue of exozodiacal dust around nearby stars. We contributed to the improvement of two near-infrared interferometers, which we used to perform the first systematic surveys of exozodiacal dust. These surveys determined their detection frequency as we
Giant Exo-Planet Atmosphere, oRigin and Dynamics – GuEPARD
How giant exo-planets form, evolve and are structured is one of the biggest challenges of modern astronomy. This major goal is directly connected to the ultimate search for Life over the Horizon 2030. Nevertheless, several astrophysical (formation, evolution, dynamics, structure and atmosphere), bio
Modelisation of stellar core collapse and birth of neutron stars and black holes – SN2NS
The scientific objective of the project SN2NS is double: elucidating the explosion mechanism of massive stars, and characterizing the birth conditions of the resulting neutron star or black hole, using a self consistant equation of state and reaction rates. The theoretical understanding of the 3D
CosmoMaterials from the Interstellar medium to the Solar system : Multi-diagnostics Experiments – COSMISME
One of the key goals in this topic is to identify, in the diversity of the encountered physico-chemical structures, the ones that would be specific or unique to some degree to a process occurring in the comple scenario of the origin and evolution of extraterrestrial organic matter, or alternatively

A remplir (20 lignes max, ~3. The success of the PAH model in astrophysics lies on the emission mechanism; following the absorption a single UV photon, PAHs could reach high enough temperatures to emit in the mid-IR bands including the 3.3 micron band. A drawback of the PAH model remains up to now
