Statistical analysis of the relative orientations between filaments and magnetic fields using Herschel and Planck data in star-forming regions
Jonathan Oers, Isabelle Ristorcelli, Katia Ferrière +4

Chemical exploration of Galactic cold cores
Chenlin Zhou, Charlotte Vastel, Julien Montillaud +6
A solar-type system starts from an initial molecular core that acquires organic complexity as it evolves. The so-called prestellar cores that can be studied are rare, which has ham…
3D extinction mapping of the Milky Way using Convolutional Neural Networks: Presentation of the method and demonstration in the Carina Arm region
D. Cornu, J. Montillaud, D. J. Marshall +2
Context. Several methods have been proposed to build 3D extinction maps of the Milky Way (MW), most often based on Bayesian approaches. Although some studies employed machine learn…
Deciphering the evolution of the Milky Way discs: Gaia APOGEE Kepler giant stars and the Besançon Galaxy Model

We investigate the properties of the double sequences of the Milky Way discs visible in the [/Fe] vs [Fe/H] diagram. In the framework of Galactic formation and evolution, we dis…
Characterization of dense Planck clumps observed with Herschel and SCUBA-2
E. Mannfors, M. Juvela, L. Bronfman +15
We aim to characterize a diverse selection of dense, potentially star-forming cores, clumps, and clouds within the Milky Way in terms of their dust emission and SF activity. We stu…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Detection of extremely high density compact structure of prestellar cores and multiple substructures within
Dipen Sahu, Sheng-Yuan Liu, Tie Liu +38
Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protost…
A neural network-based methodology to select young stellar object candidates from IR surveys
David Cornu, Julien Montillaud
Observed Young Stellar Objects (YSOs) are used to study star formation and characterize star forming regions. For this purpose, YSO candidate catalogs are compiled from various sur…
