Star Formation on the scales of galaxies
Star Formation is at the very core of the evolution of galaxies. From their gas reservoir (filled by infall or fusions), stars form at the "Star Formation Rate" (SFR),... -
H-2, H-3(+) and the age of molecular clouds and prestellar cores
International audience -
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... -
Chemical and physical characterization of the first stages of protoplanetary ...
Low mass stars, like our Sun, are born from the collapse of a molecular cloud. The matter falls in the center of the cloud, creating a protoplanetary disk surrounding... -

VLT/X-shooter spectroscopy of the GRB 090926A afterglow
12 pages, 8 .ps figures, accepted for publication in A&A. Abstract reduced due to space constraints -
Formation of stars and star clusters in colliding galaxies
Mergers are known to be essential in the formation of large-scale structures and to have a significant role in the history of galaxy formation and evolution. Besides a... -
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... -
Ionization impact on molecular clouds and star formation Numerical simulation...
At all the scales of Astrophysics, the impact of the ionization from massive stars is a crucial issue. At the galactic scale, the ionization can regulate star... -

MHD Disk wind molecular signatures from young low mass stellar objects
The origin of protostellar jets, and their role in extracting angular momentum from the accreting system, remain major open questions in star formation research. We... -
Analytical and numerical study of the flows surrounding forming stars
This thesis is built in two distinct parts, treating of two different <br />astrophysical topics: i) in the first (and main) part, work related to star formation... -
The M33 CO(2-1) survey - Star formation and molecular clouds formation

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... -
AGN and star formation history in high redshift radio galaxies
Powerful radio galaxies are excellent candidates for investigating and ultimately understanding the formation and evolution of galaxies. These beacons are now observed... -
Non-ideal magnetohydrodynamics in low-mass star formation
Stars formation occurs in several steps. First a large scale phase during which the molecular cloud undergo fragmentation due to its self-gravity and turbulence. In... -
