Squeezing the halo bispectrum: a test of bias models
Azadeh Moradinezhad Dizgah, Kwan Chuen Chan, Jorge Noreña +2
We study the halo-matter cross bispectrum in the presence of primordial non-Gaussianity of the local type. We restrict ourselves to the squeezed limit, for which the calculation ar…
The Halo Boltzmann Equation
Matteo Biagetti, Vincent Desjacques, Alex Kehagias +2
Dark matter halos are the building blocks of the universe as they host galaxies and clusters. The knowledge of the clustering properties of halos is therefore essential for the und…
What We Can Learn from the Running of the Spectral Index if no Tensors are Detected in the Cosmic Microwave Background Anisotropy
Matteo Biagetti, Alex Kehagias, Antonio Riotto
In this paper we operate under the assumption that no tensors from inflation will be measured in the future by the dedicated experiments and argue that, while for single-field slow…
Scale-dependent bias from an inflationary bispectrum: the effect of a stochastic moving barrier
Matteo Biagetti, Vincent Desjacques
With the advent of large scale galaxy surveys, constraints on primordial non-Gaussianity (PNG) are expected to reach . In order to fully exploit the p…
