We have studied the filaments extracted from the column density maps of the nearby Lupus 1, 3, and 4 molecular clouds, derived from photometric maps observed with the Herschel sate…
The CHESS survey of the L1157-B1 bow-shock: high and low excitation water vapor
G. Busquet, B. Lefloch, M. Benedettini +9
Molecular outflows powered by young protostars strongly affect the kinematics and chemistry of the natal molecular cloud through strong shocks resulting in substantial modification…

D. Polychroni, E. Schisano, D. Elia +23
We present the Herschel Gould Belt survey maps of the L1641 molecular clouds in Orion A. We extracted both the filaments and dense cores in the region. We identified which of dense…

D. Elia, S. Molinari, Y. Fukui +17
We present the first Herschel PACS and SPIRE photometric observations in a portion of the outer Galaxy ( and $-2^{\circ} \lesssi…
A Hi-GAL study of the high-mass star-forming region G29.96-0.02
M. T. Beltran, L. Olmi, R. Cesaroni +9
Context. G29.96-0.02 is a high-mass star-forming cloud observed at 70, 160, 250, 350, and 500 microns as part of the Herschel survey of the Galactic Plane during the Science Demons…
Herschel observations of B1-bS and B1-bN: two first hydrostatic core candidates in the Perseus star-forming cloud
Stefano Pezzuto, D. Elia, E. Schisano +24
We report far-IR Herschel observations obtained between 70 m and 500 m of two star-forming dusty condensations, B1-bS and B1-bN, in the B1 region of the Perseus star-forming…
The CHESS survey of the L1157-B1 shock: the dissociative jet shock as revealed by Herschel--PACS
Milena Benedettini, Gemma Busquet, Bertrand Lefloch +10
Outflows generated by protostars heavily affect the kinematics and chemistry of the hosting molecular cloud through strong shocks that enhance the abundance of some molecules. L115…
A 100-parsec elliptical and twisted ring of cold and dense molecular clouds revealed by Herschel around the Galactic Center
S. Molinari, J. Bally, A. Noriega-Crespo +38
Thermal images of cold dust in the Central Molecular Zone of the Milky Way, obtained with the far-infrared cameras on-board the Herschel satellite, reveal a 3x10^7 solar masses rin…
Water in Star-Forming Regions with the Herschel Space Observatory (WISH): Overview of key program and first results
E. F. van Dishoeck, L. E. Kristensen, A. O. Benz +12
`Water In Star-forming regions with Herschel' (WISH) is a key program on the Herschel Space Observatory designed to probe the physical and chemical structure of young stellar objec…
Source extraction and photometry for the far-infrared and sub-millimeter continuum in the presence of complex backgrounds
