A deep ALMA image of the Hubble Ultra Deep Field
Ivison, R. J.; Scott, D.; van Kampen, E. +36 more
We present the results of the first, deep Atacama Large Millimeter Array (ALMA) imaging covering the full ≃4.5 arcmin2 of the Hubble Ultra Deep Field (HUDF) imaged with Wide Field Camera 3/IR on HST. Using a 45-pointing mosaic, we have obtained a homogeneous 1.3-mm image reaching σ1.3 ≃ 35 µJy, at a resolution of ≃0.7 a…
Deriving a multivariate αCO conversion function using the [C II]/CO (1-0) ratio and its application to molecular gas scaling relations
Genzel, R.; Sturm, E.; Tacconi, L. J. +17 more
We present Herschel PACS observations of the [C II] 158 µm emission line in a sample of 24 intermediate mass (9 < log M*/M⊙ < 10) and low metallicity (0.4 < Z/Z⊙ < 1.0) galaxies from the xCOLD GASS survey. In combination with IRAM CO (1-0) measurements, we establish scaling relations between integ…
The Hi-GAL compact source catalogue - I. The physical properties of the clumps in the inner Galaxy (-71.0° < ℓ < 67.0°)
Martin, P. G.; Natoli, P.; Paladini, R. +83 more
Hi-GAL (Herschel InfraRed Galactic Plane Survey) is a large-scale survey of the Galactic plane, performed with Herschel in five infrared continuum bands between 70 and 500 µm. We present a band-merged catalogue of spatially matched sources and their properties derived from fits to the spectral energy distributions (SEDs) and heliocentric dis…
The dust mass in Cassiopeia A from a spatially resolved Herschel analysis
De Looze, I.; Rho, J.; Gomez, H. L. +4 more
Theoretical models predict that core-collapse supernovae (CCSNe) can be efficient dust producers (0.1-1.0 M⊙), potentially accounting for most of the dust production in the early Universe. Observational evidence for this dust production efficiency is however currently limited to only a few CCSN remnants (e.g. SN 1987A, Crab nebula). In …
The Herschel-ATLAS: a sample of 500 µm-selected lensed galaxies over 600 deg2
Ivison, R. J.; Omont, A.; Danese, L. +43 more
We present a sample of 80 candidate strongly lensed galaxies with flux density above 100 mJy at 500 µm extracted from the Herschel Astrophysical Terahertz Large Area Survey, over an area of 600 deg2. Available imaging and spectroscopic data allow us to confirm the strong lensing in 20 cases and to reject it in one case. For other …
Multitemperature mapping of dust structures throughout the Galactic Plane using the PPMAP tool with Herschel Hi-GAL data
Palmeirim, P.; Schneider, N.; Becciani, U. +13 more
We describe new Hi-GAL based maps of the entire Galactic Plane, obtained using continuum data in the wavelength range 70-500 µm. These maps are derived with the PPMAP procedure, and therefore represent a significant improvement over those obtained with standard analysis techniques. Specifically they have greatly improved resolution (12 arcse…
HELP: XID+, the probabilistic de-blender for Herschel SPIRE maps
Le Floc'h, E.; Valtchanov, I.; Wang, L. +13 more
We have developed a new prior-based source extraction tool, XID+, to carry out photometry in the Herschel SPIRE (Spectral and Photometric Imaging Receiver) maps at the positions of known sources. XID+ is developed using a probabilistic Bayesian framework that provides a natural framework in which to include prior information, and uses the Bayesian…
Characterizing the UV-to-NIR shape of the dust attenuation curve of IR luminous galaxies up to z ∼ 2
Buat, V.; Burgarella, D.; Efstathiou, A. +4 more
In this work, we investigate the far-ultraviolet (UV) to near-infrared (NIR) shape of the dust attenuation curve of a sample of IR-selected dust obscured (ultra)luminous IR galaxies at z ∼ 2. The spectral energy distributions (SEDs) are fitted with Code Investigating GALaxy Emission, a physically motivated spectral-synthesis model based on energy …
Evolution of cosmic star formation in the SCUBA-2 Cosmology Legacy Survey
Scott, D.; Dunlop, J. S.; Farrah, D. +19 more
We present a new exploration of the cosmic star formation history and dust obscuration in massive galaxies at redshifts 0.5 < z < 6. We utilize the deepest 450- and 850-µm imaging from SCUBA-2 CLS, covering 230 arcmin2 in the AEGIS, COSMOS and UDS fields, together with 100-250 µm imaging from Herschel. We demonstrate t…
The SCUBA-2 Cosmology Legacy Survey: the nature of bright submm galaxies from 2 deg2 of 850-µm imaging
Bowler, R. A. A.; McLure, R. J.; Dunlop, J. S. +15 more
We present physical properties [redshifts (z), star-formation rates (SFRs) and stellar masses ({M_star})] of bright (S850 ≥ 4 mJy) submm galaxies in the ≃2 deg2 COSMOS and UDS fields selected with SCUBA-2/JCMT. We complete the galaxy identification process for all (≃2000) S/N ≥ 3.5 850-µm sources, but focus our scientif…
