The impact of theoretical assumptions in the determination of the neutrino effective number from future CMB measurements
Ludovico Capparelli, Eleonora Di Valentino, Alessandro Melchiorri +1
One of the major goals of future Cosmic Microwave Background measurements is the accurate determination of the effective number of neutrinos . Reaching an experimental…
Cornering the Planck tension with future CMB data
Fabrizio Renzi, Eleonora Di Valentino, Alessandro Melchiorri
The precise measurements of Cosmic Microwave Background Anisotropy angular power spectra made by the Planck satellite show an anomalous value for the lensing amplitude, defined by…
First cosmological constraints combining Planck with the recent gravitational-wave standard siren measurement of the Hubble constant
Eleonora Di Valentino, Alessandro Melchiorri
The recent observations of gravitational-wave and electromagnetic emission produced by the merger of the binary neutron-star system GW170817 have opened the possibility of using st…
Reducing the and tensions with Dark Matter-neutrino interactions
Eleonora Di Valentino, Céline Bøehm, Eric Hivon +1
The introduction of Dark Matter-neutrino interactions modifies the Cosmic Microwave Background (CMB) angular power spectrum at all scales, thus affecting the reconstruction of the…
A Vacuum Phase Transition Solves Tension
Eleonora Di Valentino, Eric Linder, Alessandro Melchiorri
Taking the Planck cosmic microwave background data and the more direct Hubble constant measurement data as unaffected by systematic offsets, the values of the Hubble constant …
Planck intermediate results. LIII. Detection of velocity dispersion from the kinetic Sunyaev-Zeldovich effect
Planck Collaboration, N. Aghanim, Y. Akrami +141
Using the full-mission data, we present a detection of the temperature (and therefore velocity) dispersion due to the kinetic Sunyaev-Zeldovich (kSZ) effect from clu…
Exploring Cosmic Origins with CORE: The Instrument
P. de Bernardis, P. A. R. Ade, J. J. A. Baselmans +126
We describe a space-borne, multi-band, multi-beam polarimeter aiming at a precise and accurate measurement of the polarization of the Cosmic Microwave Background. The instrument is…
Can interacting dark energy solve the tension?
Eleonora Di Valentino, Alessandro Melchiorri, Olga Mena
The answer is Yes! We indeed find that interacting dark energy can alleviate the current tension on the value of the Hubble constant between the Cosmic Microwave Background a…
Constraining Dark Energy Dynamics in Extended Parameter Space
Eleonora Di Valentino, Alessandro Melchiorri, Eric V. Linder +1
Dynamical dark energy has been recently suggested as a promising and physical way to solve the 3.4 sigma tension on the value of the Hubble constant between the direct measur…
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…
Global constraints on absolute neutrino masses and their ordering
Francesco Capozzi, Eleonora Di Valentino, Eligio Lisi +3
Within the standard three-neutrino framework, the absolute neutrino masses and their ordering (either normal, NO, or inverted, IO) are currently unknown. However, the combination o…
