Evidence of Enhanced Ionization in Protostellar Envelopes
Kamber R. Schwarz, S. Maret, M. R. A. Wells +4
Ionization is a major driver of both physical and chemical evolution in protostellar systems. Recent observations reveal substantial chemical processing in protoplanetary disks by…
The converging gas flow around the infrared dark cloud G28.3
H. Beuther, C. Gieser, H. Linz +7
Aims: The G28.37+0.07 star-forming region is a prototypical infrared dark cloud (IRDC) located at the interface of a converging gas flow. This study characterizes the properties of…
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…
ALMAGAL V. Relations between the core populations and the parent clump physical properties
D. Elia, A. Coletta, S. Molinari +54
Context. The fragmentation of massive molecular clumps into smaller, potentially star-forming cores plays a key role in the processes of high-mass star formation. The ALMAGAL proje…
Filamentary accretion flows in high-mass star-forming clouds
J. -E. Schneider, H. Beuther, C. Gieser +11
We quantify the gas flows from a scale of up to several parsecs down to the sub-parsec scale along filamentary structures in the three high-mass star-forming regions G75.78, IRAS21…
From theory to observation: understanding filamentary flows in high-mass star-forming clusters
M. R. A. Wells, R. Pillsworth, H. Beuther +2
Here we use data from multi-scale galactic MHD simulations to observe filaments and star forming clumps on 10's of pc scales and investigate flow rate relationships along, and onto…
ALMAGAL IV. Morphological comparison of molecular and thermal dust emission using the histogram of oriented gradients (HOG) method
C. Mininni, S. Molinari, J. D. Soler +46
The study of molecular line emission is crucial to unveil the kinematics and the physical conditions of gas in star-forming regions. Our aim is to quantify the reliability of using…
ALMAGAL III. Compact source catalog: Fragmentation statistics and physical evolution of the core population
A. Coletta, S. Molinari, E. Schisano +49
The mechanisms behind the fragmentation of high-mass dense clumps into compact star-forming cores are fundamental topics in current astrophysical research. The ALMAGAL survey provi…
Dynamical Accretion Flows -- ALMAGAL: Flows along filamentary structures in high-mass star-forming clusters
M. R. A. Wells, H. Beuther, S. Molinari +47
We use data from the ALMA Evolutionary Study of High Mass Protocluster Formation in the Galaxy (ALMAGAL) survey to study 100 ALMAGAL regions at 1 arsecond resolution located…
Physical and chemical complexity in high-mass star-forming regions with ALMA. I. Overview and evolutionary trends of physical properties
Caroline Gieser, Henrik Beuther, Dmitry Semenov +3
In this study, we investigate how physical properties, such as the density and temperature profiles, evolve on core scales through the evolutionary sequence during high-mass star f…
