ALMA-IMF. XXI.: NH kinematics in the G012.80 protocluster: Evidence for filament rotation and evolution

J. Salinas, A. M. Stutz, R. H. Álvarez-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…

A global view on star formation: The GLOSTAR Galactic plane survey XII. Effelsberg's continuum view and data release

Y. Gong, W. Reich, M. R. Rugel +24

Extended radio continuum emission and its linear polarization play a key role in probing large-scale structures of synchrotron and free-free emission in the Milky Way. Despite the…

CASCADE: Filamentary accretion flows in Cygnus X DR20

M. Sawczuck, H. Beuther, S. Suri +11

Aims. We investigate the role of filaments in high-mass star formation, whether gas flows from large to small scales along them, and what their properties might reveal about the re…

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 XVIII: The assembly of a star cluster: Dense NH (1-0) kinematics in the massive G351.77 protocluster

N. A. Sandoval-Garrido, A. M. Stutz, R. H. Álvarez-Gutiérrez +20

ALMA-IMF observed 15 massive protoclusters capturing multiple spectral lines and the continuum emission. We focus on the G351.77 protocluster ( 2500 M, estimated fr…

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…
