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…
Symmetries of Vector Perturbations during the de Sitter Epoch
Matteo Biagetti, Alex Kehagias, Enrico Morgante +2
We analyze the class of models where a suitable coupling between the inflaton field and the vector field gives rise to scale-invariant vector perturbations. We exploit the fact tha…
Testing the Running of non-Gaussianity through the CMB mu-distortion and the Halo Bias
Matteo Biagetti, Hideki Perrier, Antonio Riotto +1
The primordial non-Gaussianity parameters fNL and tauNL may be scale-dependent. We investigate the capability of future measurements of the CMB mu-distortion, which is very sensiti…
