Cosmological Systematics Beyond Nuisance Parameters : Form Filling Functions
T. D. Kitching, A. Amara, F. B. Abdalla +2
In the absence of any compelling physical model, cosmological systematics are often misrepresented as statistical effects and the approach of marginalising over extra nuisance syst…
Predicting spectral features in galaxy spectra from broad-band photometry
F. B. Abdalla, A. Mateus, W. A. Santos +3
We explore the prospects of predicting emission line features present in galaxy spectra given broad-band photometry alone. There is a general consent that colours, and spectral fea…
On the origin of the cosmic microwave background anisotropies
Ria Follop, Anais Rassat, Asantha Cooray +1
Suggestions have been made that the microwave background observed by COBE and WMAP and dubbed Cosmic Microwave Background (CMB) may have an origin within our own Galaxy or Earth. T…
Determining neutrino properties using future galaxy redshift surveys
F. B. Abdalla, S. Rawlings
Current measurements of the large-scale structure of galaxies are able to place an upper limit on the absolute mass scale of neutrinos. An order-of-magnitude im…
Cross-correlation of 2MASS and WMAP3: Implications for the Integrated Sachs-Wolfe effect
Anais Rassat, Kate Land, Ofer Lahav +1
We perform a cross-correlation of the Cosmic Microwave Background (CMB) using the third year Wilkinson Microwave Anisotropy Probe (WMAP) data with the 2 Micron All Sky Survey (2MAS…
The galaxy-galaxy lensing contribution to the cosmic shear two point function
Sarah Bridle, Filipe B. Abdalla
We note that galaxy-galaxy lensing by non-spherical galaxy halos produces a net anti-correlation between the shear of background galaxies and the ellipticity of foreground galaxies…
