Herschel-ATLAS: rapid evolution of dust in galaxies over the last 5 billion years
Rodighiero, G.; Ivison, R. J.; Clements, D. L. +38 more
We present the first direct and unbiased measurement of the evolution of the dust mass function of galaxies over the past 5 billion years of cosmic history using data from the Science Demonstration Phase of the Herschel-Astrophysical Terahertz Large Area Survey (Herschel-ATLAS). The sample consists of galaxies selected at 250 ?m which have reliabl…
Herschel-ATLAS: counterparts from the ultraviolet-near-infrared in the science demonstration phase catalogue
Rodighiero, G.; Ivison, R. J.; Sutherland, W. +45 more
We present a technique to identify optical counterparts of 250-µm-selected sources from the Herschel-ATLAS survey. Of the 6621 250 µm > 32-mJy sources in our science demonstration catalogue we find that ∼60 per cent have counterparts brighter than r = 22.4 mag in the Sloan Digital Sky Survey. Applying a likelihood ratio technique we…
Herschel-ATLAS: first data release of the Science Demonstration Phase source catalogues
Rodighiero, G.; Ivison, R. J.; Clements, D. L. +28 more
The Herschel Astrophysical Terahertz Large Area Survey (Herschel-ATLAS) is a survey of 550 deg2 with the Herschel Space Observatory in five far-infrared and submillimetre bands. The first data for the survey, observations of a field 4 × 4 deg2 in size, were taken during the Science Demonstration Phase (SDP), and reach a 5σ no…
Data reduction pipeline for the Hi-GAL survey
Natoli, P.; Piacentini, F.; Polenta, G. +13 more
We present the data reduction pipeline for the Herschel Infrared Galactic Plane survey (Hi-GAL). Hi-GAL is a key project of the Herschel satellite, which is mapping the inner part of the Galactic plane (|l| ≤ 70° and |b| ≤ 1°), using two Photodetector Array Camera and Spectrometer (PACS) and three Spectral and Photometric Imaging Receiver (SPIRE) …
The first release of data from the Herschel ATLAS: the SPIRE images
Rodighiero, G.; Valtchanov, I.; Ivison, R. J. +26 more
We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science Demonstration Phase (SDP) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We describe the data reduction, which poses specific challenges, both because of the large number …
Physical conditions of the interstellar medium of high-redshift, strongly lensed submillimetre galaxies from the Herschel-ATLAS
Altieri, B.; Rodighiero, G.; Valtchanov, I. +51 more
We present Herschel-Spectral and Photometric Imaging Receiver (SPIRE) Fourier transform spectrometer (FTS) and radio follow-up observations of two Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS)-detected strongly lensed distant galaxies. In one of the targeted galaxies H-ATLAS J090311.6+003906 (SDP.81), we detect [O III] 88 µm a…
Herschel-ATLAS: the link between accretion luminosity and star formation in quasar host galaxies
Rodighiero, G.; Ivison, R. J.; de Zotti, G. +28 more
We use the science demonstration field data of the Herschel Astrophysical Terahertz Large Area Survey to study how star formation, traced by the far-infrared Herschel data, is related to both the accretion luminosity and redshift of quasars selected from the Sloan Digital Sky Survey (SDSS) and the 2dF-SDSS luminous red galaxy (LRG) and Quasar Spec…
Modelling galaxy and AGN evolution in the infrared: black hole accretion versus star formation activity
Pozzi, F.; Vignali, C.; Gruppioni, C. +1 more
We present a new backward evolution model for galaxies and active galactic nuclei (AGNs) in the infrared (IR). What is new in this model is the separate study of the evolutionary properties of different IR populations (i.e. spiral galaxies, starburst galaxies, low-luminosity AGNs, 'unobscured' type 1 AGNs and 'obscured' type 2 AGNs) defined throug…
Herschel-ATLAS: statistical properties of Galactic cirrus in the GAMA-9 Hour Science Demonstration Phase Field
Rodighiero, G.; Ivison, R. J.; Clements, D. L. +35 more
We study the spectral energy distribution (SED) and the power spectrum of Galactic cirrus emission observed in the 14 deg2 Science Demonstration Phase field of the Herschel-ATLAS using Herschel and IRAS data from 100 to 500 µm. We compare the Spectral and Photometric Imaging Receiver (SPIRE) 250, 350 and 500 µm maps with IRA…
Herschel observations of the Centaurus cluster - the dynamics of cold gas in a cool core
Böhringer, H.; Fabian, A. C.; Combes, F. +15 more
Brightest cluster galaxies (BCGs) in the cores of galaxy clusters have distinctly different properties from other low-redshift massive ellipticals. The majority of the BCGs in cool-core clusters show signs of active star formation. We present observations of NGC 4696, the BCG of the Centaurus galaxy cluster, at far-infrared (FIR) wavelengths with …
