The Herschel-HIFI view of mid-IR quiet massive protostellar objects
F. Herpin, L. Chavarria, T. Jacq +9
We present Herschel/HIFI observations (WISH KP) of 14 water lines in a small sample of galactic massive protostellar objects: NGC6334I(N), DR21(OH), IRAS16272-4837, and IRAS05358+3…
The Dependence of Protostellar Luminosity on Environment in the Cygnus-X Star-Forming Complex
E. Kryukova, S. T. Megeath, J. L. Hora +7
The Cygnus-X star-forming complex is one of the most active regions of low and high mass star formation within 2 kpc of the Sun. Using mid-infrared photometry from the IRAC and MIP…
Herschel Reveals Massive Cold Clumps in NGC 7538
C. Fallscheer, M. A. Reid, J. Di Francesco +29
We present the first overview of the Herschel observations of the nearby high-mass star-forming region NGC 7538, taken as part of the Herschel imaging study of OB Young Stellar obj…
Resolving the Vela C ridge with P-ArTeMiS and Herschel
T. Hill, Ph. Andre, D. Arzoumanian +25
We present APEX/P-ArTéMiS 450μm continuum observations of RCW 36 and the adjacent ridge, a high-mass high-column density filamentary structure at the centre of the Vela C molecular…
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…
Spatial variation of the cooling lines in the Orion Bar from Herschel/PACS
J. Bernard-Salas, E. Habart, H. Arab +8
We present spatially resolved Herschel/PACS observations of the Orion Bar. We have characterise the emission of the far-infrared fine-structure lines of [CII] (158um), [OI] (63 and…
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…
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…
Herschel-HIFI observations of high-J CO lines in the NGC 1333 low-mass star-forming region
