The Cosmic Microwave Background Bispectrum and Inflation
We derive an expression for the non-Gaussian cosmic-microwave-background (CMB) statistic I3 l defined recently by Ferreira, Magueijo, and Górski in terms of the slow-roll-inflation parameters ǫ and η. This result shows that a nonzero value of I3 l in COBE would rule out single-field slow-roll inflation. A sharp change in the slope of the inflaton potential could increase the predicted value of ...

We derive an expression for the non-Gaussian cosmic microwave background ~CMB! statistic I l 3 defined recently by Ferreira, Magueijo, and Górski in terms of the slow-roll-inflation parameters e and h . This result shows that a nonzero value of I l 3 in COBE would rule out single-field slow-roll inflation. A sharp change in the slope of the inflaton potential could increase the predicted value ...
متن کاملOdd-parity cosmic microwave background bispectrum
Measurement of the CMB bispectrum, or three-point correlation function, has now become one of the principle efforts in early-Universe cosmology. Here we show that there is an odd-parity component of the CMB bispectrum that has been hitherto unexplored. We argue that odd-parity temperature-polarization bispectra can arise, in principle, through weak lensing of the CMB by chiral gravitational wav...
متن کاملLarge Scale Cosmic Microwave Background Anisotropies and Dark Energy
In this note we investigate the effects of perturbations in a dark energy component with a constant equation of state on large scale cosmic microwave background anisotropies. The inclusion of perturbations increases the large scale power. We investigate more speculative dark energy models with w < −1 and find the opposite behaviour. Overall the inclusion of perturbations in the dark energy comp...
متن کاملSupernovae, the Lensed Cosmic Microwave Background, and Dark Energy
Supernova distance and primary cosmic microwave background (CMB) anisotropy measurements provide us with powerful probes of the dark energy evolution in a flat universe, but they degrade substantially once curvature is marginalized. We show that lensed CMB polarization power spectrum measurements, accessible to next generation ground-based surveys such as SPTpol or QUIET, can remove the curvatu...
