Observational Bounds on Modified Gravity Models
Antonio De Felice, Pia Mukherjee, Yun Wang
Modified gravity provides a possible explanation for the currently observed cosmic accelaration. In this paper, we study general classes of modified gravity models. The Einstein-Hi…
Nontrivial Geometries: Bounds on the Curvature of the Universe
Laura Mersini-Houghton, Yun Wang, Pia Mukherjee +1
Probing the geometry of the universe is one of the most important endevours in cosmology. Current observational data from the Cosmic Microwave Background anisotropy (CMB), galaxy s…
Comment on `Tainted evidence: cosmological model selection versus fitting', by Eric V. Linder and Ramon Miquel (astro-ph/0702542v2)
Andrew R Liddle, Pier Stefano Corasaniti, Martin Kunz +3
In astro-ph/0702542v2, Linder and Miquel seek to criticize the use of Bayesian model selection for data analysis and for survey forecasting and design. Their discussion is based on…
Observational Constraints on Dark Energy and Cosmic Curvature
Yun Wang, Pia Mukherjee
Current observational bounds on dark energy depend on assumptions about the curvature of the universe. We present a simple and efficient method for incorporating constraints from C…
On what scale should inflationary observables be constrained?
Marina Cortês, Andrew R Liddle, Pia Mukherjee
We examine the choice of scale at which constraints on inflationary observables are presented. We describe an implementation of the hierarchy of inflationary consistency equations…
When can the Planck satellite measure spectral index running?
Cédric Pahud, Andrew R. Liddle, Pia Mukherjee +1
We use model selection forecasting to assess the ability of the Planck satellite to make a positive detection of spectral index running. We simulate Planck data for a range of assu…
