Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sagittarius B2(M) *,**
H2O+ massive star forming
2014/12/22
H2O+ has been observed in its ortho- and para- states toward the massive star forming core Sgr B2(M), located close to the Galactic center. The observations show absorption in all spiral arm clouds be...
Herschel/HIFI measurements of the ortho/para ratio in water towards Sagittarius B2(M) and W31C*
gas dust
2014/12/22
We present Herschel/HIFI observations of the fundamental rotational transitions of ortho- and para-H216O and H218O in absorption towards Sagittarius B2(M) and W31C. The ortho/para ratio in water in th...
PACS and SPIRE photometer maps of M 33: First results of the HERschel M 33 Extended Survey (HERM33ES)
M 33 Simple isothermal
2014/12/22
Context. Within the framework of the HERM33ES key program, we are studying the star forming interstellar medium in the nearby, metal-poor spiral galaxy M 33, exploiting the high resolution and s...
A high-resolution line survey of IRC +10216 with Herschel/HIFI *,** First results: Detection of warm silicon dicarbide (SiC)
carbon-rich evolved star IRC+10216
2014/12/20
We present the first results of a high-spectral-resolution survey of the carbon-rich evolved star IRC+10216 that was carried out with the HIFI spectrometer onboard Herschel. This survey covers all HIF...
Cool gas and dust in M 33: Results from the HERschel M 33 Extended Survey (HERM33ES)
M 33 cool dust
2014/12/20
We present an analysis of the first space-based far-IR-submm observations of M 33, which measure the emission from the cool dust and resolve the giant molecular cloud complexes. With roughly hal...
Far-infrared line imaging of the starburst ring in NGC 1097 with the Herschel/PACS spectrometer
Seyfert nucleus interstellar medium
2014/12/20
NGC 1097 is a nearby SBb galaxy with a Seyfert nucleus and a bright starburst ring. We study the physical properties of the interstellar medium (ISM) in the ring using spatially resolved far-infrared ...
TNOs are Cool: A survey of the trans-Neptunian region V. Physical characterization of 18 Plutinos using Herschel PACS observations
Kuiper belt objects Plutinos planetary systems observational photometric
2012/2/23
We present Herschel PACS photometry of 18 Plutinos and determine sizes and albedos for these objects using thermal modeling. We analyze our results for correlations, draw conclusions on the Plutino si...
Observation of H2O in a strongly lensed Herschel-ATLAS source at z=2.3
Galaxies: high-redshift – Galaxies: starburst – Galaxies: active – Infrared: galaxies – Submillimeter: galaxies – Radiolines: galaxies
2011/10/19
The Herschel survey, H-ATLAS, with its large areal coverage, has recently discovered a number of bright, strongly lensed high-z submillimeter galaxies. The strong magnification makes it possible to st...
Gas and dust in a submillimeter galaxy at z = 4.24 from the Herschel ATLAS
submillimeter galaxy Herschel ATLAS
2011/10/9
We report ground-based follow-up observations of the exceptional source, ID141, one the brightest sources detected so far in the H-ATLAS cosmological survey. ID141 was observed using the IRAM 30-meter...

Dust Attenuation Typical Star-Forming Galaxies High Redshift: Observations Galaxies
2011/10/9
We take advantage of the sensitivity and resolution of Herschel at 100 and 160 micron to directly image the thermal dust emission and investigate the infrared luminosities, L(IR), and dust obscuration...
Herschel/HerMES: The X-ray - Infrared correlation for star-forming galaxies at z~1
X-ray - Infrared correlation star-forming galaxies
2011/9/29
For the first time, we investigate the X-ray/infrared (IR) correlation for star-forming galaxies at z~1, using SPIRE submm data from the recently-launched Herschel Space Observatory and deep X-ray dat...
Feasibility and performances of compressed-sensing and sparse map-making with Herschel/PACS data
compressed-sensing sparse map-making Herschel/PACS data
2011/1/4
The Herschel Space Observatory of ESA was launched in May 2009 and is in operation since. From its distant orbit around L2 it needs to transmit a huge quantity of information through a very limited ba...
