Quantum Origin of the Primordial Fluctuation Spectrum and its Statistics
Quantum Origin Primordial Fluctuation Spectrum Statistics
2011/10/9
The account of the origin of cosmic structure, as provided by the standard inflationary paradigm, is not fully satisfactory, as has been argued in Perez et al 2006. The central point of that work is t...
A study of relative velocity statistics in Lagrangian perturbation theory with PINOCCHIO
cosmology large-scale structure, methods analytical numerical
2010/11/11
Subject of this paper is a careful and detailed analysis of the PINOCCHIO algorithmfor studying
the relative velocity statistics of merging haloes in Lagrangian perturbation theory. Given
a cosmolog...
CMB statistics in noncommutative inflation
Cosmological inflation Statistical anisotropy of the cosmic microwave background Scale-dependent non-Gaussianity
2010/11/12
Noncommutative geometry can provide effective description of physics at very short distances taking into account generic effects of quantum gravity. Inflation amplifies tiny quantum fluctuations in th...

Excursion Sets Non-Gaussian Void Statistics
2010/11/11
Primordial non-Gaussianity (NG) affects the large scale structure (LSS) of the universe by leaving an imprint on the distribution of matter at late times. Much attention has been focused on using the ...
RFI excision using a higher order statistics analysis of the power spectrum
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/24
A method of radio frequency interference (RFI) suppression in radio astronomy spectral observations is described based on the analysis of the probability distribution of an instantaneous spectrum.
Not So Black? The Statistics of Albedo and Energy Recirculation on Hot Exoplanets
data analysis — (stars:) planetary systems
2010/3/8
[Abridged] We use a simple analytic model to analyze all of the published photometric observations of exoplanets. Our model has two parameters: the planets' Bond albedo, A, and its heat recirculation ...
