On the effect of projections on convergence peak counts and Minkowski functionals
Zoe Vallis, Chris Wallis, Tom Kitching
The act of projecting data sampled on the surface of the celestial sphere onto a regular grid on the plane can introduce error and a loss of information. This paper evaluates the e…
Space-quality data from balloon-borne telescopes: the High Altitude Lensing Observatory (HALO)
Jason Rhodes, Benjamin Dobke, Jeffrey Booth +36
We present a method for attaining sub-arcsecond pointing stability during sub- orbital balloon flights, as designed for in the High Altitude Lensing Observatory (HALO) concept. The…
Figures of Merit for Testing Standard Models: Application to Dark Energy Experiments in Cosmology
Adam Amara, Thomas Kitching
Given a standard model to test, an experiment can be designed to: (i) measure the standard model parameters; (ii) extend the standard model; or (iii) look for evidence of deviation…
Weak lensing forecasts for dark energy, neutrinos and initial conditions
Ivan Debono, Anais Rassat, Alexandre Refregier +2
Weak gravitational lensing provides a sensitive probe of cosmology by measuring the mass distribution and the geometry of the low redshift universe. We show how an all-sky weak len…
Fisher Matrix Decomposition for Dark Energy Prediction
T. D. Kitching, A. Amara
Within the context of constraining an expansion of the dark energy equation of state w(z) we show that the eigendecomposition of Fisher matrices is sensitive to both the maximum or…
Cloud Cosmology : Building the Web Interface for iCosmo
Thomas Kitching, Adam Amara, Anais Rassat +1
Astronomy and cosmology have embraced the internet. We routinely and successfully use the internet as a repository for sharing code, publications and information, and as a computat…
