The MIST team gathers researchers with very different and remarkably complementary fields of competence.

Edith Falgarone (PI) (Emeritus Director of Research, CNRS) is an expert on the physics of the interstellar medium and star formation, with a particular emphasis on turbulence and magnetic fields. She has a broad experience in millimetre and sub-millimetre molecular line observations. She has a decades-long expertise in leading many original studies to disclose the signatures of intermit- tency of cosmic turbulence, its impact on the physics of the ISM and on star-formation. She was part of the Herschel/HIFI consortium and joined the Planck collaboration for the analyses of the Galactic foregrounds. She is leading the ALMA and NOEMA collaborations on the molecular line observations of starburst galaxies (CH+, OH+ and H2O+). The MIST project is a final touch on the long-sought link between intermittency of turbulence and emergence of structures in the ISM. She will ensure the coordination between the different team members and their research axes. She will devote 80% of her research time to that project.

François Boulanger (Director of Research, CNRS) is an expert in the physics of the interstellar medium. He has an extensive experience in data analysis, in the modelling of dust and gas obser- vations, and in the characterisation of the interstellar medium structure. He was the PI of the ERC advanced grant MISTIC focused on the analysis of Planck polarisation data, studying the structure of the magnetised interstellar medium, and characterising dust emission as a foreground to CMB polarisation. He will contribute to the MIST work on the magnetic field structure, the JWST H2 observations and the modelling of the formation of turbulent H2 gas within hot plasma.

Benjamin Godard (Assistant-Astronomer, Observatoire de Paris) is specialised in the numerical modelling of the interstellar medium. He completed his PhD in 2010 on the study of out-of-equilibrium chemistry in dissipative structures of turbulence, during which he built the TDR (Turbulent Dissipa- tion Region) model. He has since been developing all the major state-of-the-art models of interstellar chemistry and radiative transfer, including the Meudon PDR (Photo Dominated Regions) code and the Paris-Durham shock code. He will lead the theoretical work on irradiated shocks and on the re- duction of chemical network for their integration in numerical simulations.

Guillaume Pineau des Forêts (Emeritus Professor, Université de Paris-Sud) is an expert on shock mod- elling and the complex gas physics taking place in the interstellar media of galaxies. His specific interest for this proposal lies in understanding how energy is transferred between bulk motions to turbulence, and how its dissipation impacts the phase balance.

Pierre Lesaffre (Assistant Researcher, CNRS) is a numericist and theoretical physicist who aims at understanding the coupling between gas dynamics and thermochemistry. His contributions range from stellar interiors (convection theories, stellar evolution and pre-supernova phases), proto-planetary disks (magnetorotational instability and planet formation), star formation (protostellar and prestellar core collapse), winds, jets and shocks in the interstellar medium, to the properties of the turbulent diffuse interstellar medium (decaying MHD turbulence and its dissipation, ambipolar diffusion). He has participated in the development of a number of codes for astrophysical fluid dynamics which are widely used in the community: the Paris-Durham stationary shock code, the RAMSES and ZEUS 3D MHD codes, the STARS and MESA stellar evolution codes.

Pierre Hily-Blant (Assistant-Professor, Université de Grenoble) is studying the evolution of in- terstellar clouds into stars and planets, with a special emphasis on the evolution of the volatile content. He is an expert in interstellar chemistry and observations of turbulence in molecular clouds. He performs radioastronomy observations with a high success at all facilities in the field, including forefront instruments (IRAM, ALMA). He is also an expert in time-dependent physico-chemical models and line radiative transfer.

François Levrier (Assistant-Professor, Ecole Normale Supérieure de Paris) focuses his research on the statistical analysis of emission maps from the Galactic interstellar medium. He has recently applied this expertise to Planck maps of polarised thermal dust emission, which not only represent a very valuable tool for understanding the astrophysics of the ISM, but also for the proper interpretation of the cosmological signal. His research interests range from the diffuse ISM to star formation with an emphasis on advanced statistical methods.
