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…
Deconstructing Baryon Acoustic Oscillations: A Comparison of Methods
Anais Rassat, Adam Amara, Luca Amendola +6
The Baryon Acoustic Oscillations (BAOs) or baryon wiggles which are present in the galaxy power spectrum at scales 100-150Mpc/h are powerful features with which to constrain cosmol…
The focal plane instrumentation for the DUNE mission
Jeff Booth, Mark Cropper, Frank Eisenhauer +2
DUNE (Dark Universe Explorer) is a proposed mission to measure parameters of dark energy using weak gravitational lensing The particular challenges of both optical and infrared foc…
Summary of the DUNE Mission Concept
Alexandre Refregier, Marian Douspis, the DUNE collaboration
The Dark UNiverse Explorer (DUNE) is a wide-field imaging mission concept whose primary goal is the study of dark energy and dark matter with unprecedented precision. To this end,…
Full-Sky Weak Lensing Simulation with 70 Billion Particles
Romain Teyssier, Sandrine Pires, Simon Prunet +7
We have performed a 70 billion dark-matter particles N-body simulation in a 2 Gpc periodic box, using the concordance, cosmological model as favored by the latest WMAP3 re…
First catalog of strong lens candidates in the COSMOS field
Cecile Faure, Jean-Paul Kneib, Giovanni Covone +19
We present the first catalog of 67 strong galaxy-galaxy lens candidates discovered in the 1.64 square degree Hubble Space Telescope COSMOS survey. Twenty of these systems display m…
