Water deuteration in star-forming regions : Contribution of Herschel/HIFI spe...
Water (H2O) is one of the most abundant molecules in the interstellar medium. In addition to being a primordial ingredient in the emergence of life, this species plays... -
Deuterium/hydrogen exchanges in interstellar ices
The interstellar medium where stars are formed consists of a dilute gas which is dominated by molecular hydrogen and dust grains less than a few microm in size. The... -
Physical and chemical evolution of polycyclic aromatic hydrocarbons in photod...
Polycyclic aromatic hydrocarbons (PAHs) play a major role in the physics and chemistry of photodissociation regions (PDRs) in our galaxy. In these environments, the... -

Les anomalies des rapports R₁₂ = I(F =1-1)/I(F =2-1) et R₀₂ = I(F =0-1)/I(F =2-1) des raies de HCN et HNN⁺ sont : modélisées par un modèle de transfert du rayonnement... -
The Local Interstellar Medium: test region and foreground.
The three-dimensional distribution of the interstellar matter (or interstellar medium, ISM) in the Galaxy is a very general tool not yet really developed today, a... -
Turbulence and thermal instability in the neutral and atomic interstellar med...
One of the main current questions in Astrophysics is the understanding of the star formation process, directly related to the processes involved in the cooling and the... -

How do the large-scale dynamics of galaxy interactions trigger star formation...
The Antennae (22 Mpc) is one of the most well-known mergers in the nearby Universe. Its distance allow us to observe and study the gas at the scales of stellar cluster... -
Theoretical studies about an extraterrestrial origin of prebiotic species
The hunt for prebiotic species in the interstellar medium is a major concern for understanding the possible role of interstellar chemistry in the synthesis of the... -

Influence of baryonic physics in simulations of disc galaxies
The modelling of baryonic physics in numerical simulations of disc galaxies allows to study the evolution of the diff erent components, the physical state of the gas... -
Physical and Chemical Conditions in the Horsehead Photodissociation Region
Molecular lines are used to trace the structure of the interstellar medium and the physical conditions of the gas in different environments, from high-z galaxies to...
