ALMA-QUARKS view of W49N: Multipolar episodic outflow associated with the most energetic Galactic water maser

Yunfan Jiao, Tie Liu, Wenyu Jiao +28

We present a detailed investigation of a multipolar episodic molecular outflow in the mini-starburst region W49N, which hosts the most luminous water maser in the Galaxy. Using hig…

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 II. The ALMA evolutionary study of high-mass protocluster formation in the Galaxy. ALMA data processing and pipeline

Á. 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…

ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions XVII. High-mass star-formation through a large-scale collapse in IRAS 153945358

Swagat R. Das, Manuel Merello, Leonardo Bronfman +23

Hub-filament systems are considered as natural sites for high-mass star formation. Kinematic analysis of the surroundings of hub-filaments is essential to better understand high-ma…

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…
