Model selection as a science driver for dark energy surveys
Pia Mukherjee, David Parkinson, Pier Stefano Corasaniti +2
A key science goal of upcoming dark energy surveys is to seek time evolution of the dark energy. This problem is one of {\em model selection}, where the aim is to differentiate bet…
Super-acceleration as Signature of Dark Sector Interaction
Subinoy Das, Pier Stefano Corasaniti, Justin Khoury
We show that an interaction between dark matter and dark energy generically results in an effective dark energy equation of state of w<-1. This arises because the interaction alter…
Testing Dark Energy with the Advanced Liquid-Mirror Probe of Asteroids, Cosmology and Astrophysics
Pier Stefano Corasaniti, Marilena LoVerde, Arlin Crotts +1
The Advanced Liquid-Mirror Probe of Asteroids, Cosmology and Astrophysics (ALPACA) is a proposed 8-meter liquid mirror telescope surveying 1000 square degree of the southern-hemisp…
Tracking Dark Energy with the ISW effect: short and long-term predictions
Levon Pogosian, Pier Stefano Corasaniti, Christian Stephan-Otto +2
We present an analysis of the constraining power of future measurements of the Integrated Sachs-Wolfe (ISW) effect on models of the equation of state of dark energy as a function o…
Constraining dark energy with cross-correlated CMB and Large Scale Structure data
P. S. Corasaniti, T. Giannantonio, A. Melchiorri
We investigate the possibility of constraining dark energy with the Integrated Sachs Wolfe effect recently detected by cross-correlating the WMAP maps with several Large Scale Stru…
Gravitational waves, inflation and the cosmic microwave background: towards testing the slow-roll paradigm
Carlo Ungarelli, Pier Stefano Corasaniti, R. A. Mercer +1
One of the fundamental and yet untested predictions of inflationary models is the generation of a very weak cosmic background of gravitational radiation. We investigate the sensiti…
