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. ...
An overview of the Dwarf Galaxy Survey
(The Astronomical Society of the Pacific, 2013)
The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galax-
ies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and
spectroscopic observations of the Herschel Space Observatory and ...
Galaxy and mass assembly: evolution of the Hα luminosity function and star formation rate density up to z < 0.35
(OUP, 2013)
Measurements of the low-z Hα luminosity function, Φ, have a large dispersion in the local number density of sources (∼0.5–1 Mpc−3 dex−1), and correspondingly in the star formation rate density (SFRD). The possible causes ...
Gama/H-Atlas: The dust opacity-stellar mass surface density relation for spiral galaxies
(IOP Science, 2013)
We report the discovery of a well-defined correlation between B-band face-on central optical depth due to dust and the stellar mass surface density of nearby spiral galaxies. This relation was derived from a sample of ...
H-Atlas: The cosmic abundance of dust from the far-infrared background power spectrum
(IOP Science, 2013)
We present a measurement of the angular power spectrum of the cosmic far-infrared background
(CFIRB) anisotropies in one of the extragalactic fields of the Herschel Astrophysical Terahertz Large
Area Survey (H-ATLAS) at ...
Comparison of Hi and optical redshifts of galaxies - The impact of redshift uncertainties on spectral line stacking
(Oxford University Press, 2013)
Accurate optical redshifts will be critical for spectral co-adding techniques used
to extract detections from below the noise level in ongoing and upcoming surveys for
Hi, which will extend our current understanding of ...
Evolution of faint radio sources in the VIDEO-XMM3 field
(OUP, 2013)
It has been speculated that low luminosity radio-loud AGN have the potential to serve
as an important source of AGN feedback, and may be responsible for suppressing
star-formation activity in massive elliptical galaxies ...
Constraining the bright-end of the UV luminosity function for z ~ 7-9 galaxies: results from CANDELS/GOODS-South
(OUP, 2013)
The recent Hubble Space Telescope near-infrared imaging with the Wide-Field Camera
#3 (WFC3) of the GOODS-South field in the CANDELS program covering nearly
100 arcmin2, along with already existing Advanced Camera for ...
Clustering of quintessence on horizon scales and its imprint on HI intensity mapping
(IOP Science, 2013)
Quintessence can cluster only on horizon scales. What is the effect on the observed matter distribution? To answer this, we need a relativistic approach that goes beyond the standard Newtonian
calculation and deals properly ...
H2O emission in high-z ultra-luminous infrared galaxies
(edp sciences, 2013)
Using the IRAM Plateau de Bure interferometer (PdBI), we report the detection of water vapor in six new lensed ultraluminous
starburst galaxies at high redshift, discovered in the Herschel Astrophysical Terahertz Large ...
