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…
Magnetic field morphological diagnostics with ALMA in the G327.29 protocluster: VGT versus dust polarization
A. Koley, A. M. Stutz, A. Lazarian +7
Magnetic fields and turbulence may play a key role in the evolution of protoclusters, influencing the formation of dense cores and stars. Here, we examine the morphology of the mag…
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…
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…
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…
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 XIV: Free-Free Templates Derived from H and Ionized Gas Content in Fifteen Massive Protoclusters
Roberto Galván-Madrid, Daniel J. Díaz-González, Frédérique Motte +25
We use the H recombination line to create templates of the millimeter free-free emission in the ALMA-IMF continuum maps, which allows to separate it from dust emission. This m…
ALMA-IMF XIII: NH kinematic analysis on the intermediate protocluster G353.41
R. H. Álvarez-Gutiérrez, A. M. Stutz, N. Sandoval-Garrido +23
The ALMA-IMF Large Program provides multi-tracer observations of 15 Galactic massive protoclusters at matched sensitivity and spatial resolution. We focus on the dense gas kinemati…
Turbulence measurements in the neutral ISM from Hi-21 cm emission-absorption spectra
Atanu Koley
We study the correlation between the non-thermal velocity dispersion () and the length-scale (L) in the neutral interstellar medium (ISM) using a large number of Hi ga…
Studying the internal structures of the central region of prestellar core L1517B in Taurus molecular cloud using ammonia (NH_3 ) (1,1) and (2,2) lines
Atanu Koley
Measurement of internal structures in the prestellar core is essential for understanding the initial conditions prior to star formation. In this work,, we study the ammonia lines (…
