Null tests of the cosmological constant using supernovae
(American Physical Society, 2014)
The standard concordance model of the Universe is based on the cosmological constant as the
driver of accelerating expansion. This concordance model is being subjected to a growing range
of inter-locking observations. ...
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 ...
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 ...
Optical-faint, far-infrared-bright Herschel sources in the CANDELS fields: Ultra-luminous infrared galaxies at z > 1 and the effect of source blending
(American Astronomical Society, 2014)
The Herschel very wide-field surveys have charted hundreds of square degrees in multiple far-IR
(FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical
counterpart identifications ...
Foreground contamination in Lyα intensity mapping during the epoch of reoinization
(IOP Science, 2014)
The intensity mapping of Lyα emission during the epoch of reionization will be contaminated by foreground
emission lines from lower redshifts. We calculate the mean intensity and the power spectrum of Lyα emission at
z ...
A critical look at the mass-metallicity-star formation rate relation in the local universe. I. An improved analysis framework and confounding systematics
(Institute of Physics Publishing, 2014)
It has been proposed that the (stellar) mass-(gas) metallicity relation of galaxies exhibits a secondary dependence on star formation rate (SFR), and that the resulting M∗-Z-SFR relation may be redshift-invariant, i.e., ...
Unpacking physics representations: Towards an appreciation of disciplinary affordance
(American Physical Society, 2014)
This theoretical article problematizes the access to disciplinary knowledge that different physics
representations have the possibility to provide; that is, their disciplinary affordances. It is argued that
historically ...
Recalibrating the Wide-field Infrared Survey Explorer (WISE) W4 Filter
(Cambridge University Press, 2014)
We present a revised effective wavelength and photometric calibration for the Wide-field Infrared Survey Explorer
W4 band, including tests of empirically motivated modifications to its pre-launch laboratory-measured ...
