First polarization study of the M87 jet and active galactic nuclei at submillimeter wavelengths with ALMA
Ciriaco Goddi, Douglas F. Carlos
We present full-polarization observations at mm (345 GHz) conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) toward Messier 87 (M87) and seven other r…
Understanding star formation in molecular clouds IV. Column density PDFs from quiescent to massive molecular clouds
N. Schneider, V. Ossenkopf-Okada, S. Clarke +26
We present N-PDFs of 29 Galactic regions obtained from Herschel imaging at high angular resolution, covering diffuse and quiescent clouds, and those showing low-, intermediate-, an…
OMC-1 dust polarisation in ALMA Band 7: Diagnosing grain alignment mechanisms in the vicinity of Orion Source I
Kate Pattle, Shih-Ping Lai, Melvyn Wright +22
We present ALMA Band 7 polarisation observations of the OMC-1 region of the Orion molecular cloud. We find that the polarisation pattern observed in the region is likely to have be…
The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
The Herschel view of star formation in the Rosette molecular cloud under the influence of NGC 2244
N. Schneider, F. Motte, S. Bontemps +43
The Rosette molecular cloud is promoted as the archetype of a triggered star-formation site. This is mainly due to its morphology, because the central OB cluster NGC 2244 has blown…
Small-scale structure in the Rosette molecular cloud revealed by Herschel
J. Di Francesco, S. Sadavoy, F. Motte +40
We present a preliminary analysis of the small-scale structure found in new 70-520 micron continuum maps of the Rosette molecular cloud (RMC), obtained with the SPIRE and PACS inst…
Herschel-SPIRE observations of the Polaris flare : structure of the diffuse interstellar medium at the sub-parsec scale
M. -A. Miville-Deschênes, P. G. Martin, A. Abergel +42
We present a power spectrum analysis of the Herschel-SPIRE observations of the Polaris flare, a high Galactic latitude cirrus cloud midway between the diffuse and molecular phases.…
Herschel observations of embedded protostellar clusters in the Rosette Molecular Cloud
M. Hennemann, F. Motte, S. Bontemps +39
The Herschel OB young stellar objects survey (HOBYS) has observed the Rosette molecular cloud, providing an unprecedented view of its star formation activity. These new far-infrare…
A Herschel study of the properties of starless cores in the Polaris Flare dark cloud region using PACS and SPIRE
D. Ward-Thompson, J. M. Kirk, P. André +32
The Polaris Flare cloud region contains a great deal of extended emission. It is at high declination and high Galactic latitude. It was previously seen strongly in IRAS Cirrus emis…
Herschel-SPIRE spectroscopy of G29.96-0.02: fitting the full SED
J. M. Kirk, E. Polehampton, L. D. Anderson +42
We use the SPIRE Fourier-Transform Spectrometer (FTS) on-board the ESA Herschel Space Telescope to analyse the submillimetre spectrum of the Ultra-compact HII region G29.96-0.02. S…
Star formation triggered by HII regions in our Galaxy: First results for N49 from the Herschel infrared survey of the Galactic plane
A. Zavagno, L. D. Anderson, D. Russeil +18
It has been shown that by means of different physical mechanisms the expansion of HII regions can trigger the formation of new stars of all masses. This process may be important to…
Mapping the column density and dust temperature structure of IRDCs with Herschel
N. Peretto, G. A. Fuller, R. Plume +22
Infrared dark clouds (IRDCs) are cold and dense reservoirs of gas potentially available to form stars. Many of these clouds are likely to be pristine structures representing the in…
Hi-GAL: the Herschel infrared Galactic Plane Survey
S. Molinari, the Hi-GAL Consortium
Hi-GAL, the Herschel infrared Galactic Plane Survey, is an Open Time Key Project of the Herschel Space Observatory. It will make an unbiased photometric survey of the inner Galacti…
