Bounces, turnarounds and singularities in bimetric gravity
Salvatore Capozziello, Prado Martin-Moruno
In this letter, we consider cosmological solutions of bimetric theory without assuming that only one metric is coupled to gravity. We conclude that any cosmology can be described b…
Updated constraints on gravity from cosmography
Alejandro Aviles, Alessandro Bravetti, Salvatore Capozziello +1
We address the issue of constraining the class of able to reproduce the observed cosmological acceleration, by using the so called cosmography of the universe. We…
Search for Gravitational Waves from Binary Black Hole Inspiral, Merger and Ringdown in LIGO-Virgo Data from 2009-2010
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +800
We report a search for gravitational waves from the inspiral, merger and ringdown of binary black holes (BBH) with total mass between 25 and 100 solar masses, in data taken at the…
Wormholes supported by hybrid metric-Palatini gravity
Salvatore Capozziello, Tiberiu Harko, Tomi S. Koivisto +2
Recently, a modified theory of gravity was presented, which consists of the superposition of the metric Einstein-Hilbert Lagrangian with an term constructed à la Palati…
Cosmology of hybrid metric-Palatini f(X)-gravity
Salvatore Capozziello, Tiberiu Harko, Tomi S. Koivisto +2
A new class of modified theories of gravity, consisting of the superposition of the metric Einstein-Hilbert Lagrangian with an term constructed à la Palatini was propos…
Constraints on massive gravity theory from big bang nucleosynthesis
G. Lambiase
The massive gravity cosmology is studied in the scenario of big bang nucleosynthesis. By making use of current bounds on the deviation from the fractional mass, we derive the const…
Einstein@Home all-sky search for periodic gravitational waves in LIGO S5 data
J. Aasi, J. Abadie, B. P. Abbott +794
This paper presents results of an all-sky searches for periodic gravitational waves in the frequency range [50, 1190] Hz and with frequency derivative ranges of [-2 x 10^-9, 1.1 x…
On the stability of the Einstein Static Universe in Massive Gravity
Luca Parisi, Ninfa Radicella, Gaetano Vilasi
We consider static cosmological solutions along with their stability properties in the framework of a recently proposed theory of massive gravity. We show that the modifcation intr…
Testing gravitational theories using Eccentric Eclipsing Detached Binaries
Mariafelicia De Laurentis, Rosario De Rosa, Fabio Garufi +1
In this paper we compare the effects of different theories of gravitation on the apsidal motion of a sample of Eccentric Eclipsing Detached Binary stars. The comparison is performe…
Gravitational Cherenkov Radiation from Extended Theories of Gravity
M. De Laurentis, S. Capozziello, G. Basini
We linearize the field equations for higher order theories of gravity that contain scalar invariants other than the Ricci scalar. We find that besides a massless spin-2 field (the…
Hamiltonian dynamics and Noether symmetries in Extended Gravity Cosmology
Salvatore Capozziello, Mariafelicia De Laurentis, Sergei D. Odintsov
We discuss the Hamiltonian dynamics for cosmologies coming from Extended Theories of Gravity. In particular, minisuperspace models are taken into account searching for Noether symm…
Scientific Objectives of Einstein Telescope
B. Sathyaprakash, M. Abernathy, F. Acernese +222
The advanced interferometer network will herald a new era in observational astronomy. There is a very strong science case to go beyond the advanced detector network and build detec…
Gravitationally Generated Interactions
Salvatore Capozziello, Mariafelicia De Laurentis, Luca Fabbri +1
Starting from a 5D-Riemannian manifold, we show that a reduction mechanism to 4D-spacetimes reproduces Extended Theories of Gravity (ETGs) that are direct generalizations of Einste…
Dark energy cosmology: the equivalent description via different theoretical models and cosmography tests
Kazuharu Bamba, Salvatore Capozziello, Shin'ichi Nojiri +1
We review different dark energy cosmologies. In particular, we present the CDM cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence cosmologies with Type…
New Spherically Symmetric Solutions in f(R)-gravity by Noether Symmetries
S. Capozziello, N. Frusciante, D. Vernieri
Spherical symmetry for f(R)-gravity is discussed by searching for Noether symmetries. The method consists in selecting conserved quantities in form of currents that reduce dynamics…
The characterization of Virgo data and its impact on gravitational-wave searches
J. Aasi, J. Abadie, B. P. Abbott +798
Between 2007 and 2010 Virgo collected data in coincidence with the LIGO and GEO gravitational-wave (GW) detectors. These data have been searched for GWs emitted by cataclysmic phen…
The physical foundations for the geometric structure of relativistic theories of gravitation. From General Relativity to Extended Theories of Gravity through Ehlers-Pirani-Schild approach
S. Capozziello, M. De Laurentis, L. Fatibene +1
We discuss in a critical way the physical foundations of geometric structure of relativistic theories of gravity by the so-called Ehlers-Pirani-Schild formalism. This approach prov…
Running coupling in electroweak interactions of leptons from f(R)-gravity with torsion
Salvatore Capozziello, Mariafelicia De Laurentis, Luca Fabbri +1
The f(R)-gravitational theory with torsion is considered for one family of leptons; it is found that the torsion tensor gives rise to interactions having the structure of the weak…
