• #### AzTEC half square degree survey of the SHADES fields – I : Maps, catalogues and source counts ﻿

(2010)
We present the first results from the largest deep extragalactic mm-wavelength survey undertaken to date. These results are derived from maps covering over 0.7 deg2, made at λ= 1.1 mm , using the AzTEC continuum camera ...
• #### The central region of spiral galaxies as seen by Herschel. M 81, M 99, and M 100 ﻿

(2010-07-01)
With appropriate spatial resolution, images of spiral galaxies in thermal infrared (~10 micron and beyond) often reveal a bright central component, distinct from the stellar bulge, superimposed on a disk with prominent ...
• #### GAMA/H-ATLAS: The Local Dust Mass Function and Cosmic Density as a Function of Galaxy Type - A Benchmark for Models of Galaxy Evolution ﻿

(2018-09-01)
We present the dust mass function (DMF) of 15,750 galaxies with redshift $z<0.1$, drawn from the overlapping area of the GAMA and {\it H-}ATLAS surveys. The DMF is derived using the density corrected $V_{\rm max}$ method, ...
• #### 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-ATLAS: Revealing dust build-up and decline across gas, dust and stellar mass selected samples: I. Scaling relations ﻿

(2017-02-01)
We present a study of the dust, stars and atomic gas (HI) in an HI-selected sample of local galaxies (z 80 per cent), low stellar mass sources that appear to be in the earliest stages of their evolution. We compare this ...
• #### Herschel-SPIRE observations of the disturbed galaxy NGC 4438 ﻿

(2010-07-01)
We present Herschel-SPIRE observations of the perturbed galaxy NGC 4438 in the Virgo cluster. These images reveal the presence of extra-planar dust up to ~4–5 kpc away from the galaxy's disk. The dust closely follows the ...
• #### LOFAR/H-ATLAS: A deep low-frequency survey of the Herschel-ATLAS North Galactic Pole field ﻿

(2016-10-21)
We present LOFAR High-Band Array (HBA) observations of the Herschel-ATLAS North Galactic Pole survey area. The survey we have carried out, consisting of four pointings covering around 142 square degrees of sky in the ...
• #### Mapping the interstellar medium in galaxies with Herschel/SPIRE ﻿

(2010-07-01)
The standard method of mapping the interstellar medium in a galaxy, by observing the molecular gas in the CO 1-0 line and the atomic gas in the 21-cm line, is largely limited with current telescopes to galaxies in the ...
• #### Probing the molecular interstellar medium of M82 with Herschel-SPIRE spectroscopy ﻿

(2010-07-01)
We present the observations of the starburst galaxy M82 taken with the Herschel SPIRE Fourier-transform spectrometer. The spectrum (194–671 μm) shows a prominent CO rotational ladder from J = 4–3 to 13–12 emitted by the ...
• #### 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 ...
• #### Red, redder, reddest : SCUBA-2 imaging of colour-selected \textit{Herschel} sources ﻿

(2018-06-11)
High-redshift, luminous, dusty star forming galaxies (DSFGs) constrain the extremity of galaxy formation theories. The most extreme are discovered through follow-up on candidates in large area surveys. Here we present 850 ...
• #### The SCUBA Half-Degree Extragalactic Survey (SHADES) - VIII : The Nature of Faint Submillimetre Galaxies in SHADES, SWIRE and SXDF Surveys ﻿

(2008)
We present the optical-to-submm spectral energy distributions for 33 radio & mid-IR identified submillimetre galaxies discovered via the SHADES 850μm SCUBA imaging in the Subaru-XMM Deep Field (SXDF). Optical data for the ...
• #### The space density of luminous dusty star-forming galaxies at $z>4$ : SCUBA-2 and LABOCA imaging of ultrared galaxies from $Herschel$-ATLAS ﻿

(2016-11-18)
Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at $z>4$, most of them significantly amplified by gravitational lensing. Here, we have increased the number of such DSFGs substantially, ...
• #### SPIRE imaging of M 82 : Cool dust in the wind and tidal streams ﻿

(2010-07-01)
M 82 is a unique representative of a whole class of galaxies, starbursts with superwinds, in the Very Nearby Galaxy Survey with Herschel. In addition, its interaction with the M 81 group has stripped a significant portion ...
