The Cosmological Analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure
Guido D'Amico, Jérôme Gleyzes, Nickolas Kokron +5
The Effective Field Theory of Large-Scale Structure (EFTofLSS) is a formalism that allows us to predict the clustering of Cosmological Large-Scale Structure in the mildly non-linea…
Dark Matter Interactions, Helium, and the CMB
Roland de Putter, Olivier Doré, Jérôme Gleyzes +2
The cosmic microwave background (CMB) places a variety of model-independent constraints on the strength interactions of the dominant component of dark matter with the Standard Mode…
Parametrizing modified gravity for cosmological surveys
Jérôme Gleyzes
One of the challenges in testing gravity with cosmology is the vast freedom opened when extending General Relativity. For linear perturbations, one solution consists in using the E…
The next non-Gaussianity frontier: what can a measurement with tell us about multifield inflation?
Roland de Putter, Jérôme Gleyzes, Olivier Doré
Future galaxy surveys promise to probe local primordial non-Gaussianity at unprecedented precision, . We study the implications for multifield inflation b…
Biasing and the search for primordial non-Gaussianity beyond the local type
Jérôme Gleyzes, Roland de Putter, Daniel Green +1
Primordial non-Gaussianity encodes valuable information about the physics of inflation, including the spectrum of particles and interactions. Significant improvements in our unders…
Effective Theory of Dark Energy at Redshift Survey Scales
Jérôme Gleyzes, David Langlois, Michele Mancarella +1
We explore the phenomenological consequences of general late-time modifications of gravity in the quasi-static approximation, in the case where cold dark matter is non-minimally co…
Effective Theory of Interacting Dark Energy
Jérôme Gleyzes, David Langlois, Michele Mancarella +1
We present a unifying treatment of dark energy and modified gravity that allows distinct conformal-disformal couplings of matter species to the gravitational sector. In this very g…
Modified gravity inside astrophysical bodies
Ryo Saito, Daisuke Yamauchi, Shuntaro Mizuno +2
Many theories of modified gravity, including the well studied Horndeski models, are characterized by a screening mechanism that ensures that standard gravity is recovered near astr…
A unifying description of dark energy
Jérôme Gleyzes, David Langlois, Filippo Vernizzi
We review and extend a novel approach that we introduced recently, to describe general dark energy or scalar-tensor models. Our approach relies on an ADM formulation based on the h…
Exploring gravitational theories beyond Horndeski
Jérôme Gleyzes, David Langlois, Federico Piazza +1
We have recently proposed a new class of gravitational scalar-tensor theories free from Ostrogradski instabilities, in arXiv:1404.6495. As they generalize Horndeski theories, or "g…
Resilience of the standard predictions for primordial tensor modes
Paolo Creminelli, Jérôme Gleyzes, Jorge Noreña +1
We show that the prediction for the primordial tensor power spectrum cannot be modified at leading order in derivatives. Indeed, one can always set to unity the speed of propagatio…
Healthy theories beyond Horndeski
Jérôme Gleyzes, David Langlois, Federico Piazza +1
We introduce a new class of scalar-tensor theories that extend Horndeski, or "generalized galileon", models. Despite possessing equations of motion of higher order in derivatives,…
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…
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…
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…
