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…
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…
ALMAGAL II. The ALMA evolutionary study of high-mass protocluster formation in the Galaxy. ALMA data processing and pipeline
Ã. Sánchez-Monge, C. L. Brogan, T. R. Hunter +53
The ALMAGAL Large Program has observed 1017 high-mass star-forming regions distributed throughout the Galaxy, sampling different evolutionary stages and environmental conditions. I…
ALMAGAL I. The ALMA evolutionary study of high-mass protocluster formation in the Galaxy. Presentation of the survey and early results
S. Molinari, P. Schilke, C. Battersby +73
Fundamental questions about the physics responsible for fragmenting molecular parsec-scale clumps into cores of ~1000 au are still open, that only a statistically significant inves…
Fine structure and kinematics of the ionized and molecular gas in the jet and disk around S255IR NIRS3 from high resolution ALMA observations
I. I. Zinchenko, S. -Y. Liu, Y. -N. Su
We present observations of the high-mass star-forming region S255IR, which harbors the 20 M protostar NIRS3, where a disk-mediated accretion burst was recorded severa…
Study of the high-mass star-forming region S255IR at various scales
I. I. Zinchenko, S. -Y. Liu, D. K. Ojha +2
The S255IR-SMA1 core contains the protostar NIRS3 with a mass of 20 M. Several years ago, the first burst of luminosity for massive protostars, caused by an episodic…
