CMB constraints on running non-Gaussianity
Filippo Oppizzi, Michele Liguori, Alessandro Renzi +2
We develop a complete set of tools for CMB forecasting, simulation and estimation of primordial running bispectra, arising from a variety of curvaton and single-field (DBI) models…
Peering beyond the horizon with standard sirens and redshift drift
Raul Jimenez, Alvise Raccanelli, Licia Verde +1
An interesting test on the nature of the Universe is to measure the global spatial curvature of the metric in a model independent way, at a level of , or, if possibl…
CMB bounds on tensor-scalar-scalar inflationary correlations
Maresuke Shiraishi, Michele Liguori, James R. Fergusson
The nonlinear interaction between one graviton and two scalars is enhanced in specific inflationary models, potentially leading to distinguishable signatures in the bispectrum of t…
A gravitational-wave standard siren measurement of the Hubble constant
B. P. Abbott, R. Abbott, T. D. Abbott +1308
The detection of GW170817 in both gravitational waves and electromagnetic waves heralds the age of gravitational-wave multi-messenger astronomy. On 17 August 2017 the Advanced LIGO…
Detecting higher spin fields through statistical anisotropy in the CMB and galaxy power spectra
Nicola Bartolo, Alex Kehagias, Michele Liguori +3
Primordial inflation may represent the most powerful collider to test high-energy physics models. In this paper we study the impact on the inflationary power spectrum of the comovi…
Large-scale structure in mimetic Horndeski gravity
Frederico Arroja, Teppei Okumura, Nicola Bartolo +2
In this paper, we propose to use the mimetic Horndeski model as a model for the dark universe. Both cold dark matter (CDM) and dark energy (DE) phenomena are described by a single…
BAO Extractor: bias and redshift space effects
Takahiro Nishimichi, Eugenio Noda, Marco Peloso +1
We study a new procedure to measure the sound horizon scale via Baryonic Acoustic Oscillations (BAO). Instead of fitting the measured power spectrum (PS) to a theoretical model con…
Parity breaking signatures from a Chern-Simons coupling during inflation: the case of non-Gaussian gravitational waves
Nicola Bartolo, Giorgio Orlando
Considering high-energy modifications of Einstein gravity during inflation is an interesting issue. We can constrain the strength of the new gravitational terms through observation…
Laser induced fluorescence for axion dark matter detection: a feasibility study in YLiF:Er
C. Braggio, G. Carugno, F. Chiossi +8
We present a detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models. The…
Primordial non-Gaussianity with -type and -type spectral distortions: exploiting Cosmic Microwave Background polarization and dealing with secondary sources
Andrea Ravenni, Michele Liguori, Nicola Bartolo +1
Cross-correlations between Cosmic Microwave Background (CMB) temperature and -spectral distortions anisotropies have been previously proposed as a way to measure the local bispe…
Exploring cosmic origins with CORE: mitigation of systematic effects
P. Natoli, M. Ashdown, R. Banerji +123
We present an analysis of the main systematic effects that could impact the measurement of CMB polarization with the proposed CORE space mission. We employ timeline-to-map simulati…
Exploring cosmic origins with CORE: gravitational lensing of the CMB
Anthony Challinor, Rupert Allison, Julien Carron +110
Lensing of the CMB is now a well-developed probe of large-scale clustering over a broad range of redshifts. By exploiting the non-Gaussian imprints of lensing in the polarization o…
Inflationary magnetogenesis with added helicity: constraints from non-gaussianities
Chiara Caprini, Maria Chiara Guzzetti, Lorenzo Sorbo
In previous work, two of us have proposed a model of inflationary magnetogenesis based on a rolling auxiliary field able both to account for the magnetic fields inferred by the (no…
Relativistic wide-angle galaxy bispectrum on the light-cone
Daniele Bertacca, Alvise Raccanelli, Nicola Bartolo +3
Given the important role that the galaxy bispectrum has recently acquired in cosmology and the scale and precision of forthcoming galaxy clustering observations, it is timely to de…
A Robust BAO Extractor
Eugenio Noda, Marco Peloso, Massimo Pietroni
We define a procedure to extract the oscillating part of a given nonlinear Power Spectrum, and derive an equation describing its evolution including the leading effects at all scal…
Discovery potential for directional Dark Matter detection with nuclear emulsions
N. Agafonova, A. Aleksandrov, A. Anokhina +53
Direct Dark Matter searches are nowadays one of the most fervid research topics with many experimental efforts devoted to the search for nuclear recoils induced by the scattering o…
Exploring cosmic origins with CORE: effects of observer peculiar motion
C. Burigana, C. S. Carvalho, T. Trombetti +116
We discuss the effects on the CMB, CIB, and thermal SZ effect due to the peculiar motion of an observer with respect to the CMB rest frame, which induces boosting effects. We inves…
Exploring Cosmic Origins with CORE: B-mode Component Separation
M. Remazeilles, A. J. Banday, C. Baccigalupi +113
We demonstrate that, for the baseline design of the CORE satellite mission, the polarized foregrounds can be controlled at the level required to allow the detection of the primordi…
Exploring Cosmic Origins with CORE: Cluster Science
J. -B. Melin, A. Bonaldi, M. Remazeilles +118
We examine the cosmological constraints that can be achieved with a galaxy cluster survey with the future CORE space mission. Using realistic simulations of the millimeter sky, pro…
Uncertainty in the visibility mask of a survey and its effects on the clustering of biased tracers
Manuel Colavincenzo, Pierluigi Monaco, Emiliano Sefusatti +1
The forecasted accuracy of upcoming surveys of large-scale structure cannot be achieved without a proper quantification of the error induced by foreground removal (or other systema…
