We categorized clumps, embedded clusters, and open clusters and conducted a
comparative analysis of their physical properties. Overall, the radii of open clusters are …

The initial mass–radius relation of embedded star clusters is an essential boundary
condition for understanding the evolution of embedded clusters in which stars form to their …

We use the H41α recombination line to create templates of the millimeter free–free emission
in the ALMA-IMF continuum maps, which allows us to separate it from dust emission. This …

Abstract We report high-resolution 1.3 mm continuum and molecular line observations of the
massive protostar G28. 20-0.05 with Atacama Large Millimeter/submillimeter Array. The …

To test theoretical models of massive star formation it is important to compare their
predictions with observed systems. To this end, we conduct CO molecular line radiative …

Aims. Because studies on complex organic molecules (COMs) in high-mass protostellar
outflows are sparse, we want to investigate how a powerful outflow, such as that driven by …

Abstract The Atacama Large Millimeter/submillimeter Array (ALMA) Survey of Star Formation
and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE) aims to investigate …

Star formation is ubiquitously associated with the ejection of accretion-powered outflows that
carve bipolar cavities through the infalling envelope. This feedback is expected to be …

Aims. We aim to identify and characterize cores in the high-mass protocluster W49A,
determine their evolutionary stages, and measure the associated lifetimes. Methods. We …

Despite the huge impact that high-mass stars have on galaxy environments and the stars
and planets that form within them, there is still no consensus on how they form. Some …
