Signatures of inflow motion in cores of massive star formation: Potential collapse candidates

, 2007
Using the IRAM 30 m telescope, a mapping survey in optically thick and thin lines was performed towards 46 high mass star-forming regions. The sample includes UC H{\sc ii} precursors and UC H{\sc ii} regions.

Cluster-formation in the Rosette molecular cloud at the junctions of filaments [PDF]

, 2012
For many years feedback processes generated by OB-stars in molecular clouds, including expanding ionization fronts, stellar winds, or UV-radiation, have been proposed to trigger subsequent star formation.

An Ultraviolet Study of Star-Forming Regions in M31

, 2009
We present a comprehensive study of star-forming (SF) regions in the nearest large spiral galaxy M31. We use GALEX far-UV (1344-1786 \AA, FUV) and near-UV (1771-2831 \AA, NUV) imaging to detect young massive stars and trace the recent star formation ...

Alignment Parameters: Quantifying Dense Core Alignment in Star-forming Regions

The Astrophysical Journal
Recent high-resolution observations at millimeter (mm) and submillimeter wavelengths reveal a diverse spatial distribution for subparsec-scale dense cores within star-forming regions, ranging from clustered to aligned arrangements.

The ALMA-QUARKS Survey: Fibers’ Role in Star Formation Unveiled in an Intermediate-mass Protocluster Region of the Vela D Cloud

The Astrophysical Journal
In this paper, we present a detailed analysis of the IRS 17 filament within the intermediate-mass protocluster IRAS 08448-4343 (of ∼10 ^3 L _⊙ ), using ALMA data from the ATOMS 3 mm and QUARKS 1.3 mm surveys.
