WMAP 5-year constraints on fnl with wavelets
A. Curto, E. Martinez-Gonzalez, P. Mukherjee +4
We present a Gaussianity analysis of the WMAP 5-year Cosmic Microwave Background (CMB) temperature anisotropy data maps. We use several third order estimators based on the spherica…
Planck priors for dark energy surveys
Pia Mukherjee, Martin Kunz, David Parkinson +1
Although cosmic microwave background (CMB) anisotropy data alone cannot constrain simultaneously the spatial curvature and the equation of state of dark energy, CMB data provide a…
On the degeneracy between primordial tensor modes and cosmic strings in future CMB data from Planck
Jon Urrestilla, Pia Mukherjee, Andrew R. Liddle +3
While observations indicate that the predominant source of cosmic inhomogeneities are adiabatic perturbations, there are a variety of candidates to provide auxiliary trace effects,…
Planck and reionization history: a model selection view
Pia Mukherjee, Andrew R. Liddle
We use Bayesian model selection tools to forecast the Planck satellite's ability to distinguish between different models for the reionization history of the Universe, using the lar…
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…
