Emergence of high-mass stars in complex fiber networks (EMERGE) V. From filaments to spheroids: the origin of the hub-filament systems
A. Hacar, R. Konietzka, D. Seifried +7
Identified as parsec-size, gas clumps at the junction of multiple filaments, hub-filament systems (HFS) play a crucial role during the formation of young clusters and high-mass sta…
Emergence of high-mass stars in complex fiber networks (EMERGE) III. Fiber networks in Orion
A. Socci, A. Hacar, F. Bonanomi +2
The Herschel observations unveiled the complex organisation of the interstellar medium in networks of parsec-scale filaments over the past decade. At the same time, networks of fib…
Emergence of high-mass stars in complex fiber networks (EMERGE) IV. Environmental dependence of the fiber widths
A. Socci, A. Hacar, F. Bonanomi +2
Despite their variety of scales throughout the interstellar medium, filaments in nearby low-mass clouds show a characteristic width of 0.1 pc from the analysis of {\it Hersc…
The factors that influence protostellar multiplicity I: Gas temperature, density, and mass in Perseus with Nobeyama
N. M. Murillo, C. M. Fuchs, D. Harsono +9
Protostellar multiplicity is common at all stages and mass ranges. However, the factors that determine the multiplicity of protostellar systems have not been systematically charact…
The Cygnus Allscale Survey of Chemistry and Dynamical Environments: CASCADE III. The large scale distribution of DCO+, DNC and DCN in the DR21 filament
I. Barlach Christensen, F. Wyrowski, V. S. Veena +12
Deuterated molecules and their molecular D/H-ratios (RD(D)) are important diagnostic tools to study the physical conditions of star-forming regions. The degree of deuteration, RD(D…
Emergence of high-mass stars in complex fiber networks (EMERGE) II. The need for data combination in ALMA observations
F. Bonanomi, A. Hacar, A. Socci +2
ALMA's high-resolution images allow to resolve the filamentary structure of the ISM down to few thousand au at kpc distances. We aim to systematically quantify the impact of the in…
Parsec-scale cosmic-ray ionisation rate in Orion
A. Socci, G. Sabatini, M. Padovani +2
Cosmic rays regulate the dynamics and the chemical processes in the densest and coldest regions of the ISM. Still, the determination of the cosmic-ray ionisation rate of H (${ζ…
Emergence of high-mass stars in complex fiber networks (EMERGE). I. Early ALMA Survey: observations and massive data reduction
A. Hacar, A. Socci, F. Bonanomi +10
(Abridged) Recent molecular surveys have revealed a rich gas organization of sonic-like fibers in all kind of environments prior to the formation of low- and high-mass stars. This…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Our Galaxy
Pamela Klaassen, Alessio Traficante, Maria T. Beltrán +38
As we learn more about the multi-scale interstellar medium (ISM) of our Galaxy, we develop a greater understanding for the complex relationships between the large-scale diffuse gas…
On the evolution of the observed Mass-to-Length relationship for star-forming filaments
Jiancheng Feng, Rowan J. Smith, Alvaro Hacar +2
The interstellar medium is threaded by a hierarchy of filaments from large scales (~ 100 pc) to small scales (~ 0.1pc). The masses and lengths of these nested structures may reveal…
