We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

ABSTRACT The c2d Spitzer Legacy project obtained images and photometry with both
IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds …

Context. Density and velocity fluctuations on virtually all scales observed with modern
telescopes show that molecular clouds (MCs) are turbulent. The forcing and structural …

We demonstrate the utility of dendrograms at representing the essential features of the
hierarchical structure of the isosurfaces for molecular line data cubes. The dendrogram of a …

Whether or not molecular clouds and embedded cloud fragments are stable against
collapse is of utmost importance for the study of the star formation process. Only" …

We have conducted a high-resolution imaging study of the Taurus–Auriga star-forming
region in order to characterize the primordial outcome of multiple star formation and the …

The discovery of large numbers of young low-mass stars and brown dwarfs over the past
decade has made it possible to investigate star formation and early evolution in a previously …

Abstract We present Submillimeter Array (SMA) λ= 0.88 and 1.3 mm broad-band
observations, and Very Large Array (VLA) observations in NH 3 (J, K)=(1, 1) up to (5, 5), H 2 …
