From forced collapse to H ii region expansion in Mon R2: Envelope density structure and age determination with Herschel
P. Didelon, F. Motte, P. Tremblin +32
The surroundings of HII regions can have a profound influence on their development, morphology, and evolution. This paper explores the effect of the environment on H II regions in…
First Results from High Angular Resolution ALMA Observations Toward the HL Tau Region
ALMA Partnership, C. L. Brogan, L. M. Perez +82
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission from the HL Tau region…
The W43-MM1 mini-starburst ridge, a test for star formation efficiency models
Fabien Louvet, Frédérique Motte, Patrick Hennebelle +12
Context: Star formation efficiency (SFE) theories are currently based on statistical distributions of turbulent cloud structures and a simple model of star formation from cores. Th…
The M16 molecular complex under the influence of NGC6611. Herschel's perspective of the heating effect on the Eagle Nebula
T. Hill, F. Motte, P. Didelon +25
We present Herschel images from the HOBYS key program of the Eagle Nebula (M16) in the far-infrared and sub-millimetre, using the PACS and SPIRE cameras at 70μm, 160μm, 250μm, 350μ…
HOBYS' view of Vela C and W48: a ridge and a mini-starburst
T. Hill, Q. Nguyen Luong, F. Motte +3
We present recent results from the Herschel HOBYS guaranteed time key program of the Vela C andW48 star-forming complexes. We examine the column density distribution in Vela C, in…
The Herschel view of massive star formation in G035.39--00.33: Dense and cold filament of W48 undergoing a mini-starburst
Q. Nguyen Luong, F. Motte, M. Hennemann +29
The filament IRDC G035.39--00.33 in the W48 molecular complex is one of the darkest infrared clouds observed by \textit{Spitzer}. It has been observed by the PACS (70 and 160\,$\mi…
Arcsecond resolution images of the chemical structure of the low-mass protostar IRAS 16293-2422
Jes K. Jorgensen, Tyler L. Bourke, Quang Nguyen Luong +1
It remains a key challenge to establish the molecular content of different components of low-mass protostars, like their envelopes and disks, and how this depends on the evolutiona…
W43: the closest molecular complex of the Galactic Bar?
Q. Nguyen Luong, F. Motte, F. Schuller +9
We used a large database extracted from Galaxy-wide surveys of H {\scriptsize I}, CO 1-0, $8 \micron$ and $870 \micron$ continuum to trace diffuse atomic gas, low- to medium…
