Non-Gaussianities due to Relativistic Corrections to the Observed Galaxy Bispectrum
E. Di Dio, H. Perrier, R. Durrer +4
High-precision constraints on primordial non-Gaussianity (PNG) will significantly improve our understanding of the physics of the early universe. Among all the subtleties in using…
Precision Comparison of the Power Spectrum in the EFTofLSS with Simulations
Simon Foreman, Hideki Perrier, Leonardo Senatore
We study the prediction of the dark matter power spectrum at two-loop order in the Effective Field Theory of Large Scale Structures (EFTofLSS) using high precision numerical simula…
A Consistency Relation for the Observed Galaxy Bispectrum and the Local non-Gaussianity from Relativistic Corrections
A. Kehagias, A. Moradinezhad Dizgah, J. Noreña +2
We obtain a consistency relation for the observed three-point correlator of galaxies. It includes relativistic effects and it is valid in the squeezed limit. Furthermore, the consi…
A Consistency Relation for the CMB B-mode Polarization in the Squeezed Limit
A. Kehagias, A. Moradinezhad-Dizgah, J. Noreña +2
A large-scale temperature perturbation has a non-zero correlation with the power spectrum of B-modes of cosmological origin on short scales while the corresponding correlation is e…
Equal-time Consistency Relations in the Large-Scale Structure of the Universe
Alex Kehagias, Hideki Perrier, Antonio Riotto
We discuss the consistency relations involving the soft limit of the (n + 1)-correlator functions of dark matter at equal times and their consequences for the halo model.
Consequences of Symmetries and Consistency Relations in the Large-Scale Structure of the Universe for Non-local bias and Modified Gravity
Alexandros Kehagias, Jorge Noreña, Hideki Perrier +1
Consistency relations involving the soft limit of the (n + 1)-correlator functions of dark matter and galaxy overdensities can be obtained, both in real and redshift space, thanks…
