Chemical diversity of dense cores in Orion B: The role of the environment
Helena J. Mazurek, Maryvonne Gerin, Pierre Gratier +26
Prestellar cores are the sites of the earliest stages of star formation. Dust continuum observations are often used to identify and characterize their properties yet only a small f…
The molecular diversity of the ISM in galaxies across cosmic time
Mathilde Bouvier, Yiqing Song, Michael Romano +7
Submillimetre molecular lines (e.g., CO, HCN, SiO) provide a uniquely powerful view of the physical and chemical processes that govern star formation (SF) and galaxy evolution. Yet…
Tracers of the ionization fraction in dense and translucent molecular gas: II. Using mm observations to constrain ionization fraction across Orion B
Ivana BeÅ¡liÄ, Maryvonne Gerin, Viviana V. Guzmán +28
The ionization fraction () is a crucial parameter of interstellar gas, yet estimating it requires deep knowledge of molecular gas chemistry…
Beetroots: spatially-regularized Bayesian inference of physical parameter maps -- Application to Orion
Pierre Palud, Emeric Bron, Pierre Chainais +28
The current generation of millimeter receivers is able to produce cubes of 800 000 pixels by 200 000 frequency channels to cover several square degrees over the 3 mm atmospheric wi…
The Dust Polarisation and Magnetic Field Structure in the Centre of NGC253 with ALMA
Davide Belfiori, Rosita Paladino, Annie Hughes +7
Magnetic fields have an impact on galaxy evolution at multiple scales. They are particularly important for starburst galaxies, where they play a crucial role in shaping the interst…
