Identification of molecular line emission using Convolutional Neural Networks
Nina Kessler, Timea Csengeri, David Cornu +2
Complex organic molecules (COMs) are observed to be abundant in various astrophysical environments, in particular toward star forming regions they are observed both toward protoste…
ALMA-IMF XX: Core fragmentation in the W51 high-mass star-forming region
T. Yoo, A. Ginsburg, J. Braine +27
We present a study of core fragmentation in the W51-E and W51-IRS2 protoclusters in the W51 high-mass star-forming region. The identification of core fragmentation is achieved by t…
ALMA-IMF XVII -- Census and lifetime of high-mass prestellar cores in 14 massive protoclusters
M. Valeille-Manet, S. Bontemps, T. Csengeri +24
High-mass prestellar cores are extremely rare. The search for such objects has long been hindered by small sample sizes, leading to large uncertainties in their lifetimes and the c…
SF2A Environmental Transition Commission: What kind of astrophysics research for a sustainable world?
F Cantalloube, D Barret, M Bouffard +11
During its annual conference in 2024, the French Society of Astronomy \& Astrophysics (SF2A) hosted, for the fourth time, a special session dedicated to discussing the environm…
Global and Local Infall in the ASHES Sample (GLASHES). I. Pilot Study in G337.541
Kaho Morii, Patricio Sanhueza, Timea Csengeri +4
Recent high-angular-resolution observations indicate the need for core growth to form high-mass stars. To understand the gas dynamics at the core scale in the very early evolutiona…
ALMA-IMF XVI: Mass-averaged temperature of cores and protostellar luminosities in the ALMA-IMF protoclusters
F. Motte, Y. Pouteau, T. Nony +34
ALMA-IMF imaged 15 massive protoclusters down to a resolution of of 2 kau scales, identifying about 1000 star-forming cores. The mass and luminosity of these cores, which are funda…
