Galaxy And Mass Assembly (GAMA): spectroscopic analysis
(Oxford University Press, 2013)
The Galaxy And Mass Assembly (GAMA) survey is a multiwavelength photometric and spectroscopic
survey, using the AAOmega spectrograph on the Anglo-Australian Telescope to obtain
spectra for up to _ 300 000 galaxies over ...
Evolution of star formation in the UKIDSS ultra deep survey field - I. Luminosity functions and cosmic star formation rate out of z = 1.6
(OUP, 2013)
We present new results on the cosmic star formation history in the SXDS-UDS field out to
z = 1.6. We compile narrow-band data from the Subaru Telescope and the Visible and Infrared
Survey Telescope for Astronomy (VISTA) ...
Galaxy correlations and the BAO in a void universe: structure formation as a test of the Copernican Principle
(IOP Science, 2013)
A suggested solution to the dark energy problem is the void model, where accelerated expansion is
replaced by Hubble-scale inhomogeneity. In these models, density perturbations grow on a radially
inhomogeneous background. ...
Cosmology on ultralarge scales with intensity mapping of the neutral hydrogen 21 cm emission: limits on primodial non-gaussianity
(American Physical Society, 2013)
The large-scale structure of the Universe supplies crucial information about the physical processes
at play at early times. Unresolved maps of the intensity of 21 cm emission from neutral hydrogen HI at redshifts z ~ 1 − ...
HerMES: The far-infrared emission from dust-obscured galaxies
(American Astronomical Society, 2013)
The far-infrared (far-IR) luminosities of luminous infrared
galaxies (LIRGs) and ultra-LIRGs (ULIRGs) are dominated by reprocessed thermal dust
emission, due to a combination of star formation and active
galactic nucleus ...
Herschel-ATLAS: A binary HyLIRG pinpointing a cluster of starbursting protoellipticals
(American Astronomical Society, 2013)
Panchromatic observations of the best candidate hyperluminous infrared galaxies from the widest Herschel
extragalactic imaging survey have led to the discovery of at least four intrinsically luminous z = 2.41 galaxies
across ...
The star-formation history of mass-selected galaxies from the VIDEO survey
(Oxford University Press, 2014)
We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ...
SKAO HI intensity mapping: blind foreground subtraction challenge
(University of the Western Cape, 2022)
Neutral Hydrogen Intensity Mapping (H I IM) surveys will be a powerful new probe of cosmology. However, strong astrophysical
foregrounds contaminate the signal and their coupling with instrumental systematics further ...
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
A deep search for faint galaxies associated with very low-redshift C iv absorbers: A case with cold-accretion characteristics
(The American Astronomical Society, 2013)
Studies of QSO absorber–galaxy connections are often hindered by inadequate information on whether faint/dwarf
galaxies are located near the QSO sight lines. To investigate the contribution of faint galaxies to QSO ...
