Multi-scale dynamics in star-forming regions: the interplay between gravity and turbulence
A. Traficante, G. A. Fuller, A. Duarte-Cabral +5
In the multi-scale view of the star formation process the material flows from large molecular clouds down to clumps and cores. In this paradigm it is still unclear if it is gravity…

Mid and Far-Infrared Color-Color Relations within Local Galaxies
Benjamin Gregg, Daniela Calzetti, Mark Heyer
We present an extensive archival analysis of a sample of local galaxies, combining multi-wavelength data from GALEX, Spitzer and Herschel to investigate "blue-side" mid-infrared (M…
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…
TIMES II: Investigating the Relation Between Turbulence and Star-forming Environments in Molecular Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Neal J. Evans +14
We investigate the effect of star formation on turbulence in the Orion A and Ophiuchus clouds using principal component analysis (PCA). We measure the properties of turbulence by a…
