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…
Evolution of Interstellar Medium, Star Formation, and Accretion at High Redshift
Aussel, H.; Ivison, R. J.; Ilbert, O. +20 more
ALMA observations of the long wavelength dust continuum are used to estimate the interstellar medium (ISM) masses in a sample of 708 galaxies at z = 0.3 to 4.5 in the COSMOS field. The galaxy sample has known far-infrared luminosities and, hence, star formation rates (SFRs) and stellar masses ({M}* ) from the optical-infrared spectrum f…
A Herschel/PACS Far-infrared Line Emission Survey of Local Luminous Infrared Galaxies
Sanders, D. B.; Surace, J. A.; Inami, H. +20 more
We present an analysis of [O I]63, [O III]88, [N II]122, and [C II]158 far-infrared (FIR) fine-structure line observations obtained with Herschel/PACS, for ∼240 local luminous infrared galaxies (LIRGs) in the Great Observatories All-sky LIRG Survey. We find pronounced declines ("deficits") of line-to-FIR…
The VLA-COSMOS 3 GHz Large Project: The infrared-radio correlation of star-forming galaxies and AGN to z ≲ 6
Bondi, M.; Berta, S.; Magnelli, B. +23 more
We examine the behaviour of the infrared-radio correlation (IRRC) over the range 0 <z ≲ 6 using new, highly sensitive 3 GHz observations with the Karl G. Jansky Very Large Array (VLA) and infrared data from the Herschel Space Observatory in the 2 deg2 COSMOS field. We distinguish between objects where emission is believed to arise so…
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 extragalactic background light revisited and the cosmic photon-photon opacity
Franceschini, Alberto; Rodighiero, Giulia
Context. In addition to its relevant astrophysical and cosmological significance, the extragalactic background light (EBL) is a fundamental source of opacity for cosmic high energy photons, as well as a limitation for the propagation of high-energy particles in the Universe.
Aims: We review our previously published determinations of the EBL p…
The impact of clustering and angular resolution on far-infrared and millimeter continuum observations
Daddi, Emanuele; Béthermin, Matthieu; Wu, Hao-Yi +7 more
Follow-up observations at high-angular resolution of bright submillimeter galaxies selected from deep extragalactic surveys have shown that the single-dish sources are comprised of a blend of several galaxies. Consequently, number counts derived from low- and high-angular-resolution observations are in tension. This demonstrates the importance of …
The VLA-COSMOS 3 GHz Large Project: Multiwavelength counterparts and the composition of the faint radio population
Bondi, M.; Berta, S.; Ilbert, O. +18 more
We study the composition of the faint radio population selected from the Karl G. Jansky Very Large Array Cosmic Evolution Survey (VLA-COSMOS) 3 GHz Large Project, which is a radio continuum survey performed at 10 cm wavelength. The survey covers a 2.6 square degree area with a mean rms of 2.3 µJy/beam, cataloging 10 830 sources above 5σ, and…
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 Green Bank Ammonia Survey: First Results of NH3 Mapping of the Gould Belt
Caselli, Paola; Di Francesco, James; Rosolowsky, Erik +23 more
We present an overview of the first data release (DR1) and first-look science from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-forming regions with {A}{{V}}≳ 7 mag visible from the northern hemisphere in emission from NH3 and other key molecular tracers.
