The ALMA EGO-10 Survey of Massive Protoclusters: Correlation of 1.3 mm Continuum Source Clustering with Evolutionary State
Michael C. Logue, Claudia J. Cyganowski, Crystal L. Brogan +4
Massive stars characteristically form in clustered environments. Characterising young massive 'protoclusters' is therefore crucial to constraining the mechanism(s) of massive star…
Older Ages for 23 Pre-Main Sequence Stars in Upper Scorpius Using Dynamical Mass-Constrained Stellar Evolutionary Models
Allison P. M. Towner, Joshua A. Eisner, Patrick D. Sheehan +2
We present revised stellar ages for 23 pre-main sequence K- and M-type stars in the Upper Scorpius star-forming region, derived by using stellar dynamical masses to constrain isoch…
Dynamical Masses for 23 Pre-Main Sequence Stars in Upper Scorpius: A Critical Test of Stellar Evolutionary Models
A. P. M. Towner, J. A. Eisner, P. D. Sheehan +2
We present dynamical masses for 23 pre-main sequence K- and M-type stars in the Upper Scorpius star-forming region. These masses were derived from the Keplerian rotation of CO disk…
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 XIV: Free-Free Templates Derived from H and Ionized Gas Content in Fifteen Massive Protoclusters
Roberto Galván-Madrid, Daniel J. Díaz-González, Frédérique Motte +25
We use the H recombination line to create templates of the millimeter free-free emission in the ALMA-IMF continuum maps, which allows to separate it from dust emission. This m…
ALMA-IMF XI: The sample of hot core candidates A rich population of young high-mass proto-stars unveiled by the emission of methyl formate
M. Bonfand, T. Csengeri, S. Bontemps +28
Sites associated with high-mass star and cluster formation exhibit a so-called hot core phase, characterized by high temperatures and column densities of complex organic molecules.…
ALMA-IMF IX: Catalog and Physical Properties of 315 SiO Outflow Candidates in 15 Massive Protoclusters
A. P. M. Towner, A. Ginsburg, P. Dell'Ova +24
We present a catalog of 315 protostellar outflow candidates detected in SiO J=5-4 in the ALMA-IMF Large Program, observed with ~2000 au spatial resolution, 0.339 km/s velocity reso…
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…
ALMA-IMF. V. Prestellar and protostellar core populations in the W43 cloud complex
T. Nony, R. Galvan-Madrid, F. Motte +24
The origin of the stellar initial mass function (IMF) and its relation with the core mass function (CMF) are actively debated issues with important implications in astrophysics. Re…
ALMA-IMF VI -- Investigating the origin of stellar masses: Core mass function evolution in the W43-MM2&MM3 mini-starburst
Y. Pouteau, F. Motte, T. Nony +35
Among the most central open questions regarding the initial mass function (IMF) of stars is the impact of environment on the shape of the core mass function (CMF) and thus potentia…
ALMA-IMF III -- Investigating the origin of stellar masses: Top-heavy core mass function in the W43-MM2&MM3 mini-starburst
Y. Pouteau, F. Motte, T. Nony +35
The ALMA-IMF Large Program observed the W43-MM2-MM3 ridge, whose 1.3mm and 3mm ALMA 12m array continuum images reach a 2500au spatial resolution. We used both the best-sensitivity…
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…
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…
VLA Observations of 9 Extended Green Objects in the Milky Way: Ubiquitous Weak, Compact Continuum Emission, and Multi-Epoch Emission from CHOH, HO, and NH Masers

We have observed a sample of 9 Extended Green Objects (EGOs) at 1.3 and 5 cm with the VLA with sub-arcsecond resolution and ~7-14 uJy/beam sensitivities in order to characterize ce…
The Extraordinary Outburst in the Massive Protostellar System NGC6334I-MM1: Strong Increase in Mid-Infrared Continuum Emission
T. R. Hunter, C. L. Brogan, J. M. De Buizer +7
In recent years, dramatic outbursts have been identified toward massive protostars via infrared and millimeter dust continuum and molecular maser emission. The longest lived outbur…
