A unified multiwavelength model of galaxy formation
Baugh, Carlton M.; Lagos, Claudia D. P.; Cole, Shaun +7 more
We present a new version of the GALFORM semi-analytical model of galaxy formation. This brings together several previous developments of GALFORM into a single unified model, including a different initial mass function (IMF) in quiescent star formation and in starbursts, feedback from active galactic nuclei suppressing gas cooling in massive haloes…
The Herschel-ATLAS data release 1 - I. Maps, catalogues and number counts
Ivison, R. J.; Ibar, E.; Dunne, L. +11 more
We present the first major data release of the largest single key-project in area carried out in open time with the Herschel Space Observatory. The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 600 deg2 in five photometric bands - 100, 160, 250, 350 and 500 µm - with the Photoconductor Array Camera an…
Galaxy And Mass Assembly (GAMA): Panchromatic Data Release (far-UV-far-IR) and the low-z energy budget
Holwerda, Benne W.; Wilkins, Stephen M.; Conselice, Christopher J. +63 more
We present the Galaxy And Mass Assembly (GAMA) Panchromatic Data Release (PDR) constituting over 230 deg2 of imaging with photometry in 21 bands extending from the far-UV to the far-IR. These data complement our spectroscopic campaign of over 300k galaxies, and are compiled from observations with a variety of facilities including: GALax…
A survey of the cold molecular gas in gravitationally lensed star-forming galaxies at z > 2
Murphy, E. J.; Weiss, A.; Greve, T. R. +18 more
Using the Australia Telescope Compact Array, we conducted a survey of CO J = 1 - 0 and J = 2 - 1 line emission towards strongly lensed high-redshift dusty star-forming galaxies (DSFGs) previously discovered with the South Pole Telescope (SPT). Our sample comprises 17 sources that had CO-based spectroscopic redshifts obtained with the Atacama Large…
LOFAR/H-ATLAS: a deep low-frequency survey of the Herschel-ATLAS North Galactic Pole field
Prandoni, I.; Brunetti, G.; White, G. J. +25 more
We present Low-Frequency Array (LOFAR) High-Band Array observations of the Herschel-ATLAS North Galactic Pole survey area. The survey we have carried out, consisting of four pointings covering around 142 deg2 of sky in the frequency range 126-173 MHz, does not provide uniform noise coverage but otherwise is representative of the quality…
A census of dense cores in the Taurus L1495 cloud from the Herschel
White, G. J.; André, Ph.; Könyves, V. +17 more
We present a catalogue of dense cores in a ∼4° × 2° field of the Taurus star-forming region, inclusive of the L1495 cloud, derived from Herschel SPIRE and PACS observations in the 70 µm, 160 µm, 250 µm, 350 µm, and 500 µm continuum bands. Estimates of mean dust temperature and total mass are derived using modified bla…
Star formation in quasar hosts and the origin of radio emission in radio-quiet quasars
Ho, Luis C.; Strauss, Michael A.; Heckman, Timothy M. +11 more
Radio emission from radio-quiet quasars may be due to star formation in the quasar host galaxy, to a jet launched by the supermassive black hole, or to relativistic particles accelerated in a wide-angle radiatively driven outflow. In this paper, we examine whether radio emission from radio-quiet quasars is a byproduct of star formation in their ho…
The star formation rate density from z = 1 to 6
Clements, David L.; Oliver, Seb; Vaccari, Mattia +6 more
We use 3035 Herschel-SPIRE 500 µm sources from 20.3 deg2 of sky in the HerMES Lockman, ES1 and XMM-LSS areas to estimate the star formation rate density at z = 0-6. 500 µm sources are associated first with 350 and 250 µm sources, and then with Spitzer 24 µm sources from the SWIRE photometric redshift catalogue. T…
Far-infrared and dust properties of present-day galaxies in the EAGLE simulations
Baes, Maarten; Schaye, Joop; Theuns, Tom +3 more
The Evolution and Assembly of GaLaxies and their Environments (EAGLE) cosmological simulations reproduce the observed galaxy stellar mass function and many galaxy properties. In this work, we study the dust-related properties of present-day EAGLE galaxies through mock observations in the far-infrared and submm wavelength ranges obtained with the 3…
CHIMPS: the 13CO/C18O (J = 3 → 2) Heterodyne Inner Milky Way Plane Survey
White, G. J.; Moore, T. J. T.; Plume, R. +17 more
We present the 13CO/C18O (J = 3 → 2) Heterodyne Inner Milky Way Plane Survey (CHIMPS) which has been carried out using the Heterodyne Array Receiver Program on the 15 m James Clerk Maxwell Telescope (JCMT) in Hawaii. The high-resolution spectral survey currently covers |b| ≤ 0.5° and 28° ≲ l ≲ 46°, with an angular resolution …
