Single-Field Consistency Relations of Large Scale Structure. Part III: Test of the Equivalence Principle
Paolo Creminelli, Jérôme Gleyzes, Lam Hui +2
The recently derived consistency relations for Large Scale Structure do not hold if the Equivalence Principle (EP) is violated. We show it explicitly in a toy model with two fluids…
The full CMB temperature bispectrum from single-field inflation
Zhiqi Huang, Filippo Vernizzi
We compute the full cosmic microwave background temperature bispectrum generated by nonlinearities after single-field inflation. By integrating the photon temperature at second ord…
Single-Field Consistency Relations of Large Scale Structure. Part II: Resummation and Redshift Space
Paolo Creminelli, Jérôme Gleyzes, Marko Simonović +1
We generalize the recently derived single-field consistency relations of Large Scale Structure in two directions. First, we treat the effect of the long modes (with momentum q) on…
Single-Field Consistency Relations of Large Scale Structure
Paolo Creminelli, Jorge Noreña, Marko Simonović +1
We derive consistency relations for the late universe (CDM and ΛCDM): relations between an n-point function of the density contrast δand an (n+1)-point function in the limit in whi…
Effective Field Theory of Cosmological Perturbations
Federico Piazza, Filippo Vernizzi
The effective field theory of cosmological perturbations stems from considering a cosmological background solution as a state displaying spontaneous breaking of time translations a…
Essential Building Blocks of Dark Energy
Jerome Gleyzes, David Langlois, Federico Piazza +1
We propose a minimal description of single field dark energy/modified gravity within the effective field theory formalism for cosmological perturbations, which encompasses most exi…
