The Herschel Multi-tiered Extragalactic Survey: HerMES
Altieri, B.; Aussel, H.; Elbaz, D. +101 more
The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme designed to map a set of nested fields totalling ∼380 deg2. Fields range in size from 0.01 to ∼20 deg2, using the Herschel-Spectral and Photometric Imaging Receiver (SPIRE) (at 250, 350 and 500 µm) and the Herschel-Photodetector Array Camera a…
GOODS-Herschel: the far-infrared view of star formation in active galactic nucleus host galaxies since z ≈ 3
Magnelli, B.; Lutz, D.; Altieri, B. +28 more
We present a study of the infrared properties of X-ray selected, moderate-luminosity (i.e. LX= 1042-1044 erg s-1) active galactic nuclei (AGNs) up to z ≈ 3, in order to explore the links between star formation in galaxies and accretion on to their central black holes. We use 100 and 160 µ m fluxes …
Investigations of dust heating in M81, M83 and NGC 2403 with the Herschel Space Observatory
Clements, D. L.; Roussel, H.; Cooray, A. +21 more
We use Spitzer Space Telescope and Herschel Space Observatory far-infrared data along with ground-based optical and near-infrared data to understand how dust heating in the nearby face-on spiral galaxies M81, M83 and NGC 2403 is affected by the starlight from all stars and by the radiation from star-forming regions. We find that 70/160 ?m surface …
Herschel-ATLAS: multi-wavelength SEDs and physical properties of 250 µm selected galaxies at z < 0.5
Ivison, R. J.; Clements, D. L.; Scott, D. +38 more
We present a pan-chromatic analysis of an unprecedented sample of 1402 250 µm selected galaxies at z < 0.5 (z¯=0.24) from the Herschel-ATLAS survey. We complement our Herschel 100-500 µm data with UV-K-band photometry from the Galaxy And Mass Assembly (GAMA) survey and apply the MAGPHYS energy-balance technique to produce pan-chroma…
Mapping the cold dust temperatures and masses of nearby KINGFISH galaxies with Herschel
Roussel, H.; Armus, L.; Weiss, A. +18 more
Taking advantage of the unprecedented combination of sensitivity and angular resolution afforded by the Herschel Space Observatory at far-infrared and submillimetre wavelengths, we aim to characterize the physical properties of cold dust within nearby galaxies, as well as the associated uncertainties, namely the robustness of the parameters we der…
99 Herculis: host to a circumbinary polar-ring debris disc
Duchêne, G.; Wyatt, M. C.; Matthews, B. C. +6 more
We present resolved Herschel images of a circumbinary debris disc in the 99 Herculis system. The primary is a late F-type star. The binary orbit is well characterized and we conclude that the disc is misaligned with the binary plane. Two different models can explain the observed structure. The first model is a ring of polar orbits that move in a p…
Herschel-ATLAS/GAMA: dusty early-type galaxies and passive spirals
Rodighiero, G.; Ivison, R. J.; de Zotti, G. +38 more
We present the dust properties and star formation histories of local submillimetre-selected galaxies, classified by optical morphology. Most of the galaxies are late types and very few are early types. The early-type galaxies (ETGs) that are detected contain as much dust as typical spirals, and form a unique sample that has been blindly selected a…
The Herschel Multi-tiered Extragalactic Survey: SPIRE-mm photometric redshifts
Aussel, H.; Elbaz, D.; Pérez-Fournon, I. +78 more
We investigate the potential of submm-mm and submm-mm-radio photometric redshifts using a sample of mm-selected sources as seen at 250, 350 and 500µm by the SPIRE instrument on Herschel. From a sample of 63 previously identified mm sources with reliable radio identifications in the Great Observatories Origins Deep Survey North and Lockman Ho…
The heating of dust by old stellar populations in the bulge of M31
Schinnerer, Eva; Rix, Hans-Walter; Walter, Fabian +9 more
We use new Herschel multiband imaging of the Andromeda galaxy to analyse how dust heating occurs in the central regions of galaxy spheroids that are essentially devoid of young stars. We construct a dust temperature map of M31 through fitting modified blackbodies to the Herschel data, and find that the temperature within 2 kpc rises strongly from …
Gas-rich mergers and feedback are ubiquitous amongst starbursting radio galaxies, as revealed by the VLA, IRAM PdBI and Herschel
Ivison, R. J.; Smail, Ian; Ibar, E. +14 more
We report new, sensitive observations of two z ∼ 3-3.5 far-infrared-luminous radio galaxies, 6C 1909+72 and B3 J2330+3927, in the 12CO J = 1-0 transition with the Karl Jansky Very Large Array and at 100-500 m using Herschel, alongside new and archival 12CO J = 4-3 observations from the Plateau de Bure Interferometer. We intro…
