ALMA-IMF I -- Investigating the origin of stellar masses: Introduction to the Large Program and first results
F. Motte, S. Bontemps, T. Csengeri +61
The ALMA-IMF Large Program imaged a total noncontiguous area of 53pc2, covering 15 extreme, nearby protoclusters of the Milky Way. They were selected to span relevant early protocl…
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…
Hot methanol in the [BHB2007] 11 protobinary system: hot corino versus shock origin? : FAUST V
C. Vastel, F. Alves, C. Ceccarelli +63
Methanol is a ubiquitous species commonly found in the molecular interstellar medium. It is also a crucial seed species for the building-up of the chemical complexity in star formi…
Fragmentation, rotation and outflows in the high-mass star-forming region IRAS 23033+5951. A case study of the IRAM NOEMA large program CORE
F. Bosco, H. Beuther, A. Ahmadi +23
The formation process of high-mass stars (>8M) is poorly constrained, particularly, the effects of clump fragmentation creating multiple systems and the mechanism of mass a…
ALMA-IMF XV: The core mass function in the high-mass star-formation regime
F. Louvet, P. Sanhueza, A. Stutz +38
The stellar initial mass function (IMF) is critical to our understanding of star formation and the effects of young stars on their environment. On large scales, it enables us to us…
ALMA-IMF IV -- A comparative study of the main hot cores in W43-MM1: detection, temperature and molecular composition
N. Brouillet, D. Despois, J. Molet +21
W43-MM1 is a young region, very rich in terms of high-mass star formation. We aim to systematically identify the massive cores which contain a hot core and compare their molecular…
ALMA 870 m continuum observations of HD 100546. Evidence of a giant planet on a wide orbit
D. Fedele, C. Toci, L. Maud +1
This paper reports on a new analysis of archival ALMA m dust continuum observations. Along with the previously observed bright inner ring (au), two additio…
High gas/dust size ratio indicating efficient radial drift in the mm-faint CX Tau disk
S. Facchini, E. F. van Dishoeck, C. F. Manara +7
The large majority of protoplanetary disks have very compact (AU) continuum emission at mm wavelengths. However, high angular resolution observations that resolve the…
ALMA-IMF. VII. First release of the full spectral line cubes: Core kinematics traced by DCN J=(3-2)
N. Cunningham, A. Ginsburg, R. Galván-Madrid +30
ALMA-IMF is an Atacama Large Millimeter/submillimeter Array (ALMA) Large Program designed to measure the core mass function (CMF) of 15 protoclusters chosen to span their early evo…
Disk fragmentation in high-mass star formation. High-resolution observations towards AFGL 2591-VLA 3
S. Suri, H. Beuther, C. Gieser +29
Increasing evidence suggests that, similar to their low-mass counterparts, high-mass stars form through a disk-mediated accretion process. At the same time, formation of high-mass…
An Overview of the 2014 ALMA Long Baseline Campaign
ALMA Partnership, E. B. Fomalont, C. Vlahakis +246
A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavel…
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…
The physical and chemical structure of high-mass star-forming regions. Unraveling chemical complexity with the NOEMA large program "CORE"
C. Gieser, H. Beuther, D. Semenov +30
We use sub-arcsecond resolution (0.4) observations with NOEMA at 1.37 mm to study the dust emission and molecular gas of 18 high-mass star-forming regions. We combine the…
ALMA-IMF II -- investigating the origin of stellar masses: Continuum Images and Data Processing
A. Ginsburg, T. Csengeri, R. Galván-Madrid +49
We present the first data release of the ALMA-IMF Large Program, which covers the 12m-array continuum calibration and imaging. The ALMA-IMF Large Program is a survey of fifteen den…
