Challenges in probing turbulent and magnetic support in cores: the W43-MM1 protocluster case study
M. Valeille-Manet, F. Louvet, F. Motte +13
Estimating the level of non-thermal support in cores is both challenging and crucial for constraining the earliest stages of star formation. We quantify the kinetic and magnetic su…
The 10-15 GHz radio continuum survey of the Galactic Plane with SKAO
A. Traficante, C. Mininni, F. Cavallaro +63
Star formation emerges from the complex interplay between gravity, turbulence, magnetic fields, and stellar feedback, all of which vary across spatial scales and Galactic environme…
ALMA-IMF. XXI.: NH kinematics in the G012.80 protocluster: Evidence for filament rotation and evolution
J. Salinas, A. M. Stutz, R. H. Ãlvarez-Gutiérrez +20
(abridged) We aim to characterize kinematic processes in the G012.80 protocluster. We principally focus on the NH(10) emission to trace the dense and cold gas. Additiona…
S2D2: Small-scale Significant substructure DBSCAN Detection II. Tracing episodes and gradients of star formation activity
Marta González, Isabelle Joncour, Estelle Moraux +5
We provide the community with a homogeneous catalogue of small, significant substructures (henceforth NESTs) extracted from the spatial distribution of Young Stellar Objects (YSOs)…
Projection effects in star-forming regions: I. Nearest-neighbour statistics and observational biases
A. T. Barnes, K. Morii, J. E. Pineda +9
Stars form as molecular clouds fragment into networks of dense cores, filaments, and subclusters. The characteristic spacing of these cores is a key observable imprint of fragmenta…
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…
