Herschel -ATLAS/GAMA : Dusty early-type galaxies and passive spirals
(2012-01)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 ... -

Herschel and SCUBA-2 imaging and spectroscopy of a bright, lensed submillimetre galaxy at z = 2.3
(2010)We present a detailed analysis of the far-IR properties of the bright, lensed, z = 2.3, SMG, SMM J2135-0102, using new observations with Herschel, SCUBA-2 and the VLA. These data allow us to constrain the galaxy's SED and ... -
Herschel and SCUBA-2 observations of dust emission in a sample of Planck cold clumps
(2018-04-27)Context. Analysis of all-sky Planck submillimetre observations and the IRAS 100 μm data has led to the detection of a population of Galactic cold clumps. The clumps can be used to study star formation and dust properties ... -
The Herschel ATLAS
(2010-05-01)The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 570 deg2 of the extragalactic sky, 4 times larger than all the other Herschel extragalactic ... -
Herschel ATLAS: The cosmic star formation history of quasar host galaxies
(2010)We present a derivation of the star formation rate per comoving volume of quasar host galaxies, derived from stacking analyses of far-infrared to mm-wave photometry of quasars with redshifts 0 < z < 6 and absolute I-band ... -
The Herschel Filament : a signature of the environmental drivers of galaxy evolution during the assembly of massive clusters at z=0.9
(2012)We have discovered a 2.5 Mpc (projected) long filament of infrared-bright galaxies connecting two of the three ~5x10^14 Msun clusters making up the RCS 2319+00 supercluster at z=0.9. The filament is revealed in a deep ... -
The Herschel Multi-tiered Extragalactic Survey : SPIRE-mm photometric redshifts
(2012-02-01)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 ... -
The Herschel Multi-tiered Extragalactic Survey: HerMES
(2012-08-01)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 deg 2, using the Herschel-Spectral and ... -
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 ... -
Herschel PACS and SPIRE observations of TW Hydrae association brown dwarf disks
(2012)We present Herschel SPIRE observations of the TW Hydrae association (TWA) brown dwarf disks SSSPM J1102-3431 (SS1102) and 2MASSW J1207334-393254 (2M1207). Both disks are undetected in the SPIRE 200-500 μm bands. We analyzed ... -
The Herschel PEP/HerMES luminosity function - I : Probing the evolution of PACS selected Galaxies to z sime 4
(2013-06-01)We exploit the deep and extended far-IR data sets (at 70, 100 and 160 μm) of the Herschel Guaranteed Time Observation (GTO) PACS Evolutionary Probe (PEP) Survey, in combination with the Herschel Multi-tiered Extragalactic ... -
Herschel Photometric Observations of LITTLE THINGS Dwarf Galaxies
(2021-08-02)We present here far-infrared photometry of galaxies in a sample that is relatively unexplored at these wavelengths: low-metallicity dwarf galaxies with moderate star formation rates. Four dwarf irregular galaxies from the ... -
Herschel photometric observations of the low metallicity dwarf galaxy NGC 1705
(2010-07-01)We present Herschel SPIRE and PACS photometeric observations of the low metallicity (Z ~ 0.35ΖΘ ) nearby dwarf galaxy, NGC 1705, in six wavelength bands as part of the Dwarf Galaxy Survey guaranteed time Herschel key ... -
Herschel photometric observations of the nearby low metallicity irregular galaxy NGC 6822
(2010-07-01)We present the first Herschel PACS and SPIRE images of the low-metallicity galaxy NGC 6822 observed from 70 to 500 μm and clearly resolve the H ii regions with PACS and SPIRE. We find that the ratio 250/500 is dependent ... -
Herschel protocluster survey : A search for dusty star-forming galaxies in protoclusters at z = 2-3
(2016-08-21)We present a Herschel/Spectral and Photometric Imaging Receiver (SPIRE) survey of three protoclusters at z = 2-3 (2QZCluster, HS1700, SSA22). Based on the SPIRE colours (S350/S250 and S500/S350) of 250 μm sources, we ... -
The Herschel Reference Survey
(2010-03-01)The Herschel Reference Survey is a Herschel guaranteed time key project and will be a benchmark study of dust in the nearby universe. The survey will complement a number of other Herschel key projects including large ... -
Herschel reveals a Tdust-unbiased selection of z∼ 2 ultraluminous infrared galaxies
