An ionized outflow in Orion-KL source I?
Melvyn Wright, Tomoya Hirota, Jan Forbrich +5
We present images at 6 and 14 GHz of Source I in Orion-KL. At higher frequencies, from 43 to 340 GHz, images of this source are dominated by thermal emission from dust in a 100 AU…
Clustered Formation of Massive Stars within an Ionized Rotating Disk
Roberto Galván-Madrid, Qizhou Zhang, Andrés Izquierdo +7
We present ALMA observations with a 800 au resolution and radiative-transfer modelling of the inner part ( au) of the ionized accretion flow around a compact star clu…
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…
Salt-bearing disk candidates around high-mass young stellar objects
Adam Ginsburg, Brett A. McGuire, Patricio Sanhueza +6
Molecular lines tracing the orbital motion of gas in a well-defined disk are valuable tools for inferring both the properties of the disk and the star it surrounds. Lines that aris…
Velocity-Coherent Substructure in TMC-1: Inflow and Fragmentation
Simon E. T. Smith, Rachel Friesen, Antoine Marchal +11
Filamentary structures have been found nearly ubiquitously in molecular clouds and yet their formation and evolution is still poorly understood. We examine a segment of Taurus Mole…
Discovery of non-metastable ammonia masers in Sagittarius B2
Y. T. Yan, C. Henkel, K. M. Menten +10
We report the discovery of widespread maser emission in non-metastable inversion transitions of NH toward various parts of the Sagittarius B2 molecular cloud/star forming regio…
Astrometry of variable compact radio sources: A search for Galactic black hole X-ray binaries
P. Atri, J. C. A. Miller-Jones, A. Bahramian +7
We use the Very Long Baseline Array to conduct high precision astrometry of a sample of 33 compact, flat spectrum, variable radio sources in the direction of the Galactic plane (Be…
ALMA uncovers highly filamentary structure towards the Sgr E region
J. Wallace, C. Battersby, E. A. C. Mills +7
We report on the discovery of linear filaments observed in CO(1-0) emission for a field of view toward the Sgr E star forming region centered at (l,b)=(358.720, 0.…
Evidence for an interaction between the Galactic Center clouds M0.10-0.08 and M0.11-0.11
Natalie O. Butterfield, Cornelia C. Lang, Adam Ginsburg +3
We present high-resolution (~2-3"; ~0.1 pc) radio observations of the Galactic center cloud M0.10-0.08 using the Very Large Array at K and Ka band (~25 and 36 GHz). The M0.10-0.08…
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…
The initial conditions for young massive cluster formation in the Galactic Centre: convergence of large-scale gas flows
Bethan A. Williams, Daniel L. Walker, Steven N. Longmore +12
Young massive clusters (YMCs) are compact (1 pc), high-mass (>10 M) stellar systems of significant scientific interest. Due to their rarity and rapid fo…
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…
Star Formation in the Central Molecular Zone of the Milky Way
Jonathan D. Henshaw, Ashley T. Barnes, Cara Battersby +3
The Central Molecular Zone (CMZ) is a ring-like accumulation of molecular gas in the innermost few hundred parsecs of the Milky Way, generated by the inward transport of matter dri…
Digging into the Interior of Hot Cores with ALMA (DIHCA). II. Exploring the Inner Binary (Multiple) System Embedded in G335 MM1 ALMA1
Fernando A. Olguin, Patricio Sanhueza, Adam Ginsburg +5
We observed the high-mass protostellar core G335.579-0.272 ALMA1 at au (0.05") resolution with the Atacama Large Millimeter/submillimeter Array (ALMA) at 226 GHz (with…
The APEX Large CO Heterodyne Orion Legacy Survey (ALCOHOLS). I. Survey overview
Thomas Stanke, H. G. Arce, J. Bally +29
The Orion molecular cloud complex harbours the nearest GMCs and site of high-mass star formation. Its YSO populations are thoroughly characterized. The region is therefore a prime…
