This review examines the state-of-the-art knowledge of high-mass star and massive cluster
formation, gained from ambitious observational surveys, which acknowledges the multiscale …

Although fundamental for astrophysics, the processes that produce massive stars are not
well understood. Large distances, high extinction, and short timescales of critical …

We present the current accounting of systematic effect uncertainties for the Low Frequency
Instrument (LFI) that are relevant to the 2015 release of the Planck cosmological results …

Cold dark clouds are nearby members of the densest and coldest phase in the Galactic
interstellar medium, and represent the most accessible sites where stars like our Sun are …

Context. Thanks to its excellent 5100 m high site in Chajnantor, the Atacama Pathfinder
Experiment (APEX) systematically explores the southern sky at submillimeter wavelengths …

The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). I. Pilot Survey:
Clump Fragmentation - IOPscience This site uses cookies. By continuing to use this site you …

It has been known for more than 30 years that star formation in giant molecular clouds
(GMCs) is slow, in the sense that only~ 1% of the gas forms stars every free-fall time. This …

Using images from the Spitzer Galactic Legacy Infrared Mid-Plane Survey Extraordinaire
(GLIMPSE), we have identified more than 300 extended 4.5 μm sources (Extended Green …

Infrared dark clouds (IRDCs) are dense molecular clouds seen as extinction features against
the bright mid-infrared Galactic background. Millimeter continuum maps toward 38 IRDCs …

We simulate the early stages of the evolution of turbulent, virialized, high-mass protostellar
cores, with primary attention to how cores fragment and whether they form a small or large …
