HII regions and High mass star formation High mass stars form ionized (HII) regions. These regions expand in the interstellar medium and this expansion impacts on the surrounding. This feedback is expected to be both constructive (favoring the formation of a new generation of stars) and destructive (destruction of the surrounding material). I am interested in the role of this expansion on the properties of the star formation. Learn more...

HII regions and filaments Filaments are ubiquitous in the interstellar medium. They host star formation. I am interested in the role of HII regions in the formation of filaments. Learn more...

Big Data and Machine Learning A wealth of existing data is available in our Galaxy at all wavelengths. This allows to use these data to learn properties of the sources using Machine Learning (ML) algorithms. We just started a study to see how ML can be used to describe the Galactic Star Formation. Presentation of BigSF Project : The research project entitled "Star formation with big data and machine learning (BigSF)" proposes to use the very large masses of data available on our Galaxy in order to build, through numerical learning methods, a new empirical model of stellar formation.

Distances in the Galaxy The Herschel survey of the Galactic Plane has revealed the presence of about 150 000 sources. We have been engaged in a big effort to determine the distances of these sources using available molecular data. The results are presented in a paper (Mège et al. 2020). This opens an important field for the study of star formation in the Galaxy. Learn more...
