General CMB and Primordial Bispectrum Estimation I: Mode Expansion, Map-Making and Measures of f_NL
J. R. Fergusson, M. Liguori, E. P. S. Shellard
We present a detailed implementation of two bispectrum estimation methods which can be applied to general non-separable primordial and CMB bispectra. The method exploits bispectrum…
Cosmic String Power Spectrum, Bispectrum and Trispectrum
D. M. Regan, E. P. S. Shellard
We use analytic calculations of the post-recombination gravitational effects of cosmic strings to estimate the resulting CMB power spectrum, bispectrum and trispectrum. We place a…
Axion Cosmology Revisited
Olivier Wantz, E. P. S. Shellard
The misalignment mechanism for axion production depends on the temperature-dependent axion mass. The latter has recently been determined within the interacting instanton liquid mod…
Non-Gaussianity as a Probe of the Physics of the Primordial Universe and the Astrophysics of the Low Redshift Universe
E. Komatsu, N. Afshordi, N. Bartolo +58
A new and powerful probe of the origin and evolution of structures in the Universe has emerged and been actively developed over the last decade. In the coming decade, non-Gaussiani…
