The Herschel Multi-Tiered Extragalactic Survey: source extraction and cross-identifications in confusion-dominated SPIRE images
Altieri, B.; Aussel, H.; Elbaz, D. +83 more
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 map-space so as to minimize source-blending effects. We make use of a combination of linear inversion and model selection techni…
Evolution of dust temperature of galaxies through cosmic time as seen by Herschel
Berta, S.; Magnelli, B.; Nordon, R. +112 more
We study the dust properties of galaxies in the redshift range 0.1 <~ z <~ 2.8 observed by the Herschel Space Observatory in the field of the Great Observatories Origins Deep Survey-North as part of the PACS Extragalactic Probe (PEP) and Herschel Multi-tiered Extragalactic Survey (HerMES) key programmes. Infrared (IR) luminosity (LIR
HerMES: deep galaxy number counts from a P(D) fluctuation analysis of SPIRE Science Demonstration Phase observations
Altieri, B.; Aussel, H.; Elbaz, D. +71 more
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 galaxies that comprise this background are highly confused, such that the bulk lies below the classical confusion limit. We analyse …
H-ATLAS: PACS imaging for the Science Demonstration Phase
Rodighiero, G.; Ivison, R. J.; de Zotti, G. +26 more
We describe the reduction of data taken with the PACS instrument on board the Herschel Space Observatory in the Science Demonstration Phase of the Herschel-ATLAS (H-ATLAS) survey, specifically data obtained for a 4 × 4 deg2 region using Herschel's fast-scan (60arcsecs-1) parallel mode. We describe in detail a pipeline for dat…
Herschel-ATLAS: the far-infrared-radio correlation at z < 0.5
Rodighiero, G.; Ivison, R. J.; de Zotti, G. +45 more
We use data from the Herschel-ATLAS to investigate the evolution of the far-infrared-radio correlation over the redshift range 0 < z < 0.5. Using the total far-infrared luminosity of all >5σ sources in the Herschel-ATLAS Science Demonstration Field and cross-matching these data with radio data from the Faint Images of the Radio Sky at Twe…
Herschel reveals a Tdust-unbiased selection of z ~ 2 ultraluminous infrared galaxies
Aussel, H.; Elbaz, D.; Le Floc'h, E. +69 more
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 Multi-tiered Extragalactic Survey (HerMES) project, we explore the far-infrared (IR) properties of a sample of mid-IR-selected …
Measures of star formation rates from infrared (Herschel) and UV (GALEX) emissions of galaxies in the HerMES fields
Altieri, B.; Aussel, H.; Elbaz, D. +75 more
The reliability of infrared (IR) and ultraviolet (UV) emissions to measure star formation rates (SFRs) in galaxies is investigated for a large sample of galaxies observed with the Spectral and Photometric Imaging Receiver (SPIRE) and the Photodetector Array Camera and Spectrometer (PACS) instruments on Herschel as part of the Herschel Multi-Tiered…
HerMES: SPIRE Science Demonstration Phase maps†‡
Pérez-Fournon, I.; Franceschini, A.; Bock, J. +30 more
We describe the production and verification of sky maps of the five Spectral and Photometric Imaging Receiver (SPIRE) fields observed as part of the Herschel Multi-tiered Extragalactic Survey (HerMES) during the Science Demonstration Phase (SDP) of the Herschel mission. We have implemented an iterative map-making algorithm [The SPIRE-HerMES Iterat…
Herschel-SPIRE, far-infrared properties of millimetre-bright and -faint radio galaxies
Pérez-Fournon, I.; Rodighiero, G.; Ivison, R. J. +34 more
We present the first study of the far-infrared (FIR) properties of high-redshift, radio-selected ultraluminous infrared galaxies (ULIRGs) using deep observations obtained with the Spectral and Photometric Imaging Receiver (SPIRE) from the Herschel Multi-tiered Extragalactic Survey (HerMES). These galaxies span a large range of 850-µm fluxes …
Cold dust and young starbursts: spectral energy distributions of Herschel SPIRE sources from the HerMES survey
Aussel, H.; Elbaz, D.; Valtchanov, I. +75 more
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 galaxies and active galactic nucleus dust tori are able to model the full range of SEDs measured with Herschel. We find that…
