Cardy-Verlinde entropy in Hořava-Lifshitz gravity
Orlando Luongo, Giovanni Battista Pisani, Hernando Quevedo
We investigate homogeneous cosmological models with perfect-fluid sources in the framework of the Ho\v rava-Lifshitz model for quantum gravity. We show that the Hamiltonian constra…
Large scale structures and the cubic galileon model
Sourav Bhattacharya, Konstantinos F. Dialektopoulos, Theodore N. Tomaras
The maximum size of a bound cosmic structure is computed perturbatively as a function of its mass in the framework of the cubic galileon, proposed recently to model the dark energy…
Comment on "Classification of Cosmic Scale Factor via Noether Gauge Symmetries" [Int. J. Theor. Phys. 54, 2343 (2015)]
A. Paliathanasis, K. Krishnakumar, P. G. L. Leach
We discuss the relationship between the Noether point symmetries of the geodesic Lagrangian, in a (pseudo)Riemannian manifold, with the elements of the Homothetic algebra of the sp…
On the theory and applications of modern cosmography
Peter K. S. Dunsby, Orlando Luongo
Cosmography represents an important branch of cosmology which aims to describe the universe without the need of postulating \emph{a priori} any particular cosmological model. All q…
The Archimedes experiment
Enrico Calloni, S. Caprara, Martina De Laurentis +14
Archimedes is an INFN-funded pathfinder experiment aimed at verifying the feasibility of measuring the interaction of vacuum fluctuations with gravity. The final experiment will me…
Caustics of binary gravitational lenses: from galactic haloes to exotic matter
V. Bozza, C. Melchiorre
We investigate the caustic topologies for binary gravitational lenses made up of two objects whose gravitational potential declines as . With this corresponds to power…
f(T) teleparallel gravity and cosmology
Yi-Fu Cai, Salvatore Capozziello, Mariafelicia De Laurentis +1
Over the past decades, the role of torsion in gravity has been extensively investigated along the main direction of bringing gravity closer to its gauge formulation and incorporati…
All-sky search for long-duration gravitational wave transients with LIGO
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +934
We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November…
A search of the Orion spur for continuous gravitational waves using a "loosely coherent" algorithm on data from LIGO interferometers
J. Aasi, B. P. Abbott, R. Abbott +920
We report results of a wideband search for periodic gravitational waves from isolated neutron stars within the Orion spur towards both the inner and outer regions of our Galaxy. As…
A parametrix for quantum gravity?
Giampiero Esposito
In the sixties, DeWitt discovered that the advanced and retarded Green functions of the wave operator on metric perturbations in the de Donder gauge make it possible to define clas…
Slicing black hole spacetimes
Donato Bini, Eduardo Bittencourt, Andrea Geralico +1
A general framework is developed to investigate the properties of useful choices of stationary spacelike slicings of stationary spacetimes whose congruences of timelike orthogonal…
Cosmological attractor inflation from the RG-improved Higgs sector of finite gauge theory
Emilio Elizalde, Sergei D. Odintsov, Ekaterina O. Pozdeeva +1
The possibility to construct an inflationary scenario for renormalization-group improved potentials corresponding to the Higgs sector of finite gauge models is investigated. Taking…
Extended Cosmologies
Salvatore Capozziello, Mariafelicia F. De Laurentis, Lorenzo Fatibene +2
We shall discuss cosmological models in extended theories of gravitation. We shall define a surface, called the model surface, in the space of observable parameters which character…
The Mass-Radius relation for Neutron Stars in gravity
Salvatore Capozziello, Mariafelicia De Laurentis, Ruben Farinelli +1
We discuss the Mass -Radius diagram for static neutron star models obtained by the numerical solution of modified Tolman-Oppenheimer-Volkoff equations in gravity where the L…
Can f(R) gravity contribute to (dark) radiation?
Joao Morais, Mariam Bouhmadi-Lopez, Salvatore Capozziello
We discuss the possibility that suitable modifications of gravity could account for some amount of the radiation we observe today, in addition to the possibility of explaining the…
Hybrid metric-Palatini gravity
Salvatore Capozziello, Tiberiu Harko, Tomi S. Koivisto +2
Recently, the phenomenology of f(R) gravity has been scrutinized motivated by the possibility to account for the self-accelerated cosmic expansion without invoking dark energy sour…
Scalar field cosmology modified by the Generalized Uncertainty Principle
Andronikos Paliathanasis, Supriya Pan, Souvik Pramanik
We consider quintessence scalar field cosmology in which the Lagrangian of the scalar field is modified by the Generalized Uncertainty Principle. We show that the perturbation term…
String duality transformations in gravity from Noether symmetry approach
Salvatore Capozziello, S. J. Gabriele Gionti, Daniele Vernieri
We select gravity models that undergo scale factor duality transformations. As a starting point, we consider the tree-level effective gravitational action of bosonic String…
Constraining gravity by the Large Scale Structure
Ivan de Martino, Mariafelicia De Laurentis, Salvatore Capozziello
Over the past decades, General Relativity and the concordance CDM model have been successfully tested using several different astrophysical and cosmological probes based on larg…
Earth-Moon Lagrangian points as a testbed for general relativity and effective field theories of gravity
Emmanuele Battista, Simone Dell'Agnello, Giampiero Esposito +3
In the restricted four-body problem consisting of the Earth, the Moon and the Sun as the primaries and a spacecraft as the planetoid, we take into account the solar perturbation in…
Quantum Effects on all Lagrangian Points and Prospects to Measure Them in the Earth-Moon System
Emmanuele Battista, Giampiero Esposito, Simone Dell' Agnello +1
The one-loop long distance quantum corrections to the Newtonian potential imply tiny but observable effects in the restricted three-body problem of celestial mechanics, i.e., both…
