Signatures of anisotropic sources in the trispectrum of the cosmic microwave background
Maresuke Shiraishi, Eiichiro Komatsu, Marco Peloso
Soft limits of -point correlation functions, in which one wavenumber is much smaller than the others, play a special role in constraining the physics of inflation. Anisotropic s…
Ward identities and consistency relations for the large scale structure with multiple species
Marco Peloso, Massimo Pietroni
We present fully nonlinear consistency relations for the squeezed bispectrum of Large Scale Structure. These relations hold when the matter component of the Universe is composed of…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): An Extended White Paper
PRISM Collaboration, Philippe André, Carlo Baccigalupi +140
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in May 2013 as a large-class mission for investigating within the framework of the ESA Cosmic Visio…
Parity violation in the CMB bispectrum by a rolling pseudoscalar
Maresuke Shiraishi, Angelo Ricciardone, Shohei Saga
We investigate parity-violating signatures of temperature and polarization bispectra of the cosmic microwave background (CMB) in an inflationary model where a rolling pseudoscalar…
Polarization bispectrum for measuring primordial magnetic fields
Maresuke Shiraishi
We examine the potential of polarization bispectra of the cosmic microwave background (CMB) to constrain primordial magnetic fields (PMFs). We compute all possible bispectra betwee…
On the Trispectrum of Galileon Inflation
Frederico Arroja, Nicola Bartolo, Emanuela Dimastrogiovanni +1
We present a detailed study of the trispectrum of the curvature perturbation generated within a stable, well defined and predictive theory which comprises an inflationary phase. In…
Parametrized modified gravity constraints after Planck
Bin Hu, Michele Liguori, Nicola Bartolo +1
We constrain and chameleon-type modified gravity in the framework of the Berstchinger-Zukin parametrization using the recent released Planck data, including both CMB tempera…
The Effective Field Theory of Inflation Models with Sharp Features
Nicola Bartolo, Dario Cannone, Sabino Matarrese
We describe models of single-field inflation with small and sharp step features in the potential (and sound speed) of the inflaton field, in the context of the Effective Field Theo…
Anisotropy in solid inflation
Nicola Bartolo, Sabino Matarrese, Marco Peloso +1
In the model of solid / elastic inflation, inflation is driven by a source that has the field theoretical description of a solid. To allow for prolonged slow roll inflation, the so…
The parameter space of Cubic Galileon models for cosmic acceleration
Emilio Bellini, Raul Jimenez
We use recent measurements of the expansion history of the universe to place constraints on the parameter space of cubic Galileon models, in particular we concentrate on those mode…
The Trispectrum in the Effective Theory of Inflation with Galilean symmetry
Nicola Bartolo, Emanuela Dimastrogiovanni, Matteo Fasiello
We calculate the trispectrum of curvature perturbations for a model of inflation endowed with Galilean symmetry at the level of the fluctuations around an FRW background. Such a mo…
First observational constraints on tensor non-Gaussianity sourced by primordial magnetic fields from cosmic microwave background
Maresuke Shiraishi, Toyokazu Sekiguchi
Primordial magnetic fields (PMFs) create a large squeezed-type non-Gaussianity in tensor perturbation, which generates non-Gaussian temperature fluctuations in the cosmic microwave…
Optimal bispectrum estimator and simulations of the the CMB Lensing-ISW non-Gaussian signal
Anna Mangilli, Benjamin Wandelt, Franz Elsner +1
In this paper we present the tools to optimally extract the Lensing-Integrated Sachs Wolfe (L-ISW) bispectrum signal from future CMB data. We implement two different methods to sim…
Signatures of anisotropic sources in the squeezed-limit bispectrum of the cosmic microwave background
Maresuke Shiraishi, Eiichiro Komatsu, Marco Peloso +1
The bispectrum of primordial curvature perturbations in the squeezed configuration, in which one wavenumber, , is much smaller than the other two, , pla…
Galilean invariance and the consistency relation for the nonlinear squeezed bispectrum of large scale structure
Marco Peloso, Massimo Pietroni
We discuss the constraints imposed on the nonlinear evolution of the Large Scale Structure (LSS) of the universe by galilean invariance, the symmetry relevant on subhorizon scales.…
Non-Gaussianity and CMB aberration and Doppler
Riccardo Catena, Michele Liguori, Alessio Notari +1
The peculiar motion of an observer with respect to the CMB rest frame induces a deflection in the arrival direction of the observed photons (also known as CMB aberration) and a Dop…
Multi-variate joint PDF for non-Gaussianities: exact formulation and generic approximations
Licia Verde, Raul Jimenez, Luis Alvarez-Gaume +2
We provide an exact expression for the multi-variate joint probability distribution function of non-Gaussian fields primordially arising from local transformations of a Gaussian fi…
Matter bispectrum in cubic Galileon cosmologies
Nicola Bartolo, Emilio Bellini, Daniele Bertacca +1
In this paper we obtain the bispectrum of dark matter density perturbations in the frame of covariant cubic Galileon theories. This result is obtained by means of a semi-analytic a…
