SED fitting of nearby galaxies in the Herschel Reference Survey
(Societe Francaise d'Astronomie et d'Astrophysique, 2010-12-01)
We compute UV to radio continuum spectral energy distributions of 51 nearby galaxies recently observed with SPIRE onboard Herschel and present infrared colours (in the 25-500 μm spectral range). SPIRE data of normal galaxies ...
The Deep SPIRE HerMES Survey: spectral energy distributions and their astrophysical indications at high redshift
(2010-11-01)
We present the cross-identification and source photometry techniques used to process Herschel SPIRE imaging taken as part of the Herschel Multi-Tiered Extragalactic Survey (HerMES). Cross-identifications are performed in ...
HerMES: deep galaxy number counts from a P(D) fluctuation analysis of SPIRE Science Demonstration Phase observations
(2010-11-01)
Dusty, star-forming galaxies contribute to a bright, currently unresolved cosmic far-infrared background. Deep Herschel-Spectral and Photometric Imaging Receiver (SPIRE) images designed to detect and characterize the ...
Herschel reveals a Tdust-unbiased selection of z∼ 2 ultraluminous infrared galaxies
(2010-11-01)
Using Herschel Photodetector Array Camera (PACS) and Spectral and Photometric Imaging Receiver (SPIRE) observations of Lockman Hole-North and Great Observatories Origins Deep Survey-North (GOODS-N) as part of the Herschel ...
Cold dust and young starbursts : spectral energy distributions of Herschel SPIRE sources from the HerMES survey
(2010-11-01)
We present spectral energy distributions (SEDs) for 68 Herschel sources detected at 5σ at 250, 350 and 500 μm in the HerMES SWIRE-Lockman field. We explore whether existing models for starbursts, quiescent star-forming ...
The Herschel Multi-Tiered Extragalactic Survey: source extraction and cross-identifications in confusion-dominated SPIRE images
(2010-11-01)
We present the cross-identification and source photometry techniques used to process Herschel SPIRE imaging taken as part of the Herschel Multi-Tiered Extragalactic Survey (HerMES). Cross-identifications are performed in ...
On the origin of M81 group extended dust emission
(2010-11-01)
Galactic cirrus emission at far-infrared wavelengths affects many extragalactic observations. Separating this emission from that associated with extragalactic objects is both important and difficult. In this paper we discuss ...
Radial distribution of gas and dust in spiral galaxies : the case of M 99 (NGC 4254) and M 100 (NGC 4321)
(2010-07-01)
By combining Herschel-SPIRE data with archival Spitzer, H i , and CO maps, we investigate the spatial distribution of gas and dust in the two famous grand-design spirals M 99 and M 100 in the Virgo cluster. Thanks to the ...
The Herschel-SPIRE instrument and its in-flight performance
(2010-07-01)
The Spectral and Photometric Imaging REceiver (SPIRE), is the Herschel Space Observatory`s submillimetre camera and spectrometer. It contains a three-band imaging photometer operating at 250, 350 and 500 μm, and an imaging ...
