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 ...
The in vitro effects of artificial and natural sweeteners on the immune system using whole blood culture assays
(Taylor & Francis, 2013)
This article investigates the effects of commercially available artificial (aspartame, saccharin,
sucralose) and natural sweeteners (brown sugar, white sugar, molasses) on the immune system.
Human whole blood cultures ...
Stability of an SEIR epidemic model with indepenent stochastic perturbations
(Elsevier, 2013)
For an epidemic model of the type mentioned, we prove a theorem on almost sure exponential
stability of the disease-free equilibrium. For small values of the diffusion parameter,
σ, we describe the stability of the disease ...
A fitted numerical method for singularly perturbed parabolic reaction-diffusion problems
(Spring Verlag, 2013)
This paper treats a time-dependent singularly perturbed reaction-diffusion problem. We semidiscretize the problem in time by means of the classical backward Euler method. We develop a fitted operator finite difference ...
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 ...
