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…
Linear filament and nested cluster evolution tomography (LANCET) I. Capture the evolution of dense gas in 14-parsec filament G316.8
Fengwei Xu, Ke Wang, Nicola Schneider +12
A dynamic view of mass assembly is essential for understanding the formation of massive stars and clusters. Interpreting evolutionary diagnostics from Galactic-wide surveys, howeve…
A JWST NIRCam/MIRI view of the W51A high-mass star-forming region
Taehwa Yoo, Adam Ginsburg, Nazar Budaiev +10
We present observations of the W51A region, including the massive protoclusters W51-E and W51-IRS2, with JWST in 10 NIRCam and 5 MIRI filters. In this work, we highlight the most n…
Digging into the Interior of Hot Cores with ALMA (DIHCA). VII. Disk candidates around high-mass stars and evidence of anisotropic infall
Fernando A. Olguin, Patricio Sanhueza, Yoko Oya +19
We study the kinematics of condensations in 30 fields forming high-mass stars with ALMA at a high-resolution of ~0.08'' on average (~230 au). The presence of disks is important for…
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…
