Star clusters across cosmic time

MR Krumholz, CF McKee… - Annual Review of …, 2019 - annualreviews.org
Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

From diffuse gas to dense molecular cloud cores

J Ballesteros-Paredes, P André, P Hennebelle… - Space Science …, 2020 - Springer
Molecular clouds are a fundamental ingredient of galaxies: they are the channels that
transform the diffuse gas into stars. The detailed process of how they do it is not completely …

Kinematics in young star clusters and associations with Gaia DR2

MA Kuhn, LA Hillenbrand, A Sills… - The Astrophysical …, 2019 - iopscience.iop.org
The Gaia mission has opened a new window into the internal kinematics of young star
clusters at the sub-km s− 1 level, with implications for our understanding of how star clusters …

Global hierarchical collapse in molecular clouds. Towards a comprehensive scenario

E Vázquez-Semadeni, A Palau… - Monthly Notices of …, 2019 - academic.oup.com
We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

Fibers in the NGC 1333 proto-cluster

A Hacar, M Tafalla, J Alves - Astronomy & Astrophysics, 2017 - aanda.org
Are the initial conditions for clustered star formation the same as for non-clustered star
formation? To investigate the initial gas properties in young proto-clusters we carried out a …

Slingshot mechanism in Orion: Kinematic evidence for ejection of protostars by filaments

AM Stutz, A Gould - Astronomy & Astrophysics, 2016 - aanda.org
By comparing three constituents of Orion A (gas, protostars, and pre-main-sequence stars),
both morphologically and kinematically, we derive the following conclusions. The gas …

Star cluster formation in a turbulent molecular cloud self-regulated by photoionization feedback

E Gavagnin, A Bleuler, J Rosdahl… - Monthly Notices of the …, 2017 - academic.oup.com
Most stars in the Galaxy are believed to be formed within star clusters from collapsing
molecular clouds. However, the complete process of star formation, from the parent cloud to …

High-resolution APEX/LAsMA 12CO and 13CO (3–2) observation of the G333 giant molecular cloud complex-I. Evidence for gravitational acceleration in hub-filament …

JW Zhou, F Wyrowski, S Neupane, JS Urquhart… - Astronomy & …, 2023 - aanda.org
Context. Hub-filament systems are suggested to be the birth cradles of high-mass stars and
clusters. Aims. We investigate the gas kinematics of hub-filament structures in the G333 …

ALMA-IMF-XIII. N2H+ kinematic analysis of the intermediate protocluster G353. 41

RH Álvarez-Gutiérrez, AM Stutz… - Astronomy & …, 2024 - aanda.org
The ALMA-IMF Large Program provides multi-tracer observations of 15 Galactic massive
protoclusters at a matched sensitivity and spatial resolution. We focus on the dense gas …

How do bound star clusters form?

MR Krumholz, CF McKee - Monthly Notices of the Royal …, 2020 - academic.oup.com
Gravitationally bound clusters that survive gas removal represent an unusual mode of star
formation in the Milky Way and similar spiral galaxies. While forming, they can be …
