Hydrostatic equilibrium and stellar structure in f(R)-gravity
S. Capozziello, M. De Laurentis, S. D. Odintsov +1
We investigate the hydrostatic equilibrium of stellar structure by taking into account the modi- fied Laé-Emden equation coming out from f(R)-gravity. Such an equation is obtained…
Sensitivity Studies for Third-Generation Gravitational Wave Observatories
S. Hild, M. Abernathy, F. Acernese +136
Advanced gravitational wave detectors, currently under construction, are expected to directly observe gravitational wave signals of astrophysical origin. The Einstein Telescope, a…
Black hole dynamical evolution in a Lorentz-violating spacetime
S. Esposito, G. Salesi
We consider the black hole dynamical evolution in the framework of a Lorentz-violating spacetime endowed with a Schwarzchild-like momentum-dependent metric. Large deviations from t…
Cosmography of f(R) - brane cosmology
Mariam Bouhmadi-Lopez, Salvatore Capozziello, Vincenzo F. Cardone
Cosmography is a useful tool to constrain cosmological models, in particular dark energy models. In the case of modified theories of gravity, where the equations of motion are gene…
Correspondence between Jordan-Einstein frames and Palatini-metric formalisms
Salvatore Capozziello, Farhad Darabi, Daniele Vernieri
We discuss the conformal symmetry between Jordan and Einstein frames considering their relations with the metric and Palatini formalisms for modified gravity. Appropriate conformal…
Calibration and sensitivity of the Virgo detector during its second science run
The Virgo Collaboration, T. Accadia, F. Acernese +175
The Virgo detector is a kilometer-length interferometer for gravitational wave detection located near Pisa (Italy). During its second science run (VSR2) in 2009, six months of data…
The gravity of light
G. Sparano, G. Vilasi, S. Vilasi
A solution of the old problem raised by Tolman, Ehrenfest, Podolsky and Wheeler, concerning the lack of attraction of two light pencils "moving parallel", is proposed, considering…
Testing metric-affine f(R)-gravity by relic scalar gravitational waves
S. Capozziello, R. Cianci, M. De Laurentis +1
We discuss the emergence of scalar gravitational waves in metric-affine f(R)-gravity. Such a component allows to discriminate between metric and metric-affine theories The intrinsi…
Quantum Corrections in the Group Field Theory Formulation of the EPRL/FK Models
Thomas Krajewski, Jacques Magnen, Vincent Rivasseau +2
We investigate the group field theory formulation of the EPRL/FK spin foam models. These models aim at a dynamical, i.e. non-topological formulation of 4D quantum gravity. We intro…
Characterization of the seismic environment at the Sanford Underground Laboratory, South Dakota
Jan Harms, Fausto Acernese, Fabrizio Barone +18
An array of seismometers is being developed at the Sanford Underground Laboratory, the former Homestake mine, in South Dakota to study the properties of underground seismic fields…
Equivalence between Palatini and metric formalisms of f(R)-gravity by divergence free current
Salvatore Capozziello, Farhad Darabi, Daniele Vernieri
The equivalence between metric and Palatini formalisms in f(R)-gravity can be achieved in the general context of theories with divergence free current. This equivalence is a necess…
Search for Gravitational Waves from Compact Binary Coalescence in LIGO and Virgo Data from S5 and VSR1
the LIGO Scientific Collaboration, the Virgo Collaboration
We report the results of the first search for gravitational waves from compact binary coalescence using data from the LIGO and Virgo detectors. Five months of data were collected d…
Astrophysical structures from primordial quantum black holes
S. Capozziello, G. Cristofano, M. De Laurentis
The characteristic sizes of astrophysical structures, up to the whole observed Universe, can be recovered, in principle, assuming that gravity is the overall interaction assembling…
Stability of the Einstein Static Universe in open cosmological models
Rosangela Canonico, Luca Parisi
The stability properties of the Einstein Static solution of General Relativity are altered when corrective terms arising from modification of the underlying gravitational theory ap…
Physical non-equivalence of the Jordan and Einstein frames
S. Capozziello, P. Martin-Moruno, C. Rubano
We show, considering a specific f(R)-gravity model, that the Jordan frame and the Einstein frame are physically non-equivalent, although they are connected by a conformal transform…
The Cauchy problem for metric-affine f(R)-gravity in presence of a Klein-Gordon scalar field
S. Capozziello, S. Vignolo
We study the initial value formulation of metric-affine f(R)-gravity in presence of a Klein-Gordon scalar field acting as source of the field equations. Sufficient conditions for t…
All-sky search for gravitational-wave bursts in the first joint LIGO-GEO-Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration
We present results from an all-sky search for unmodeled gravitational-wave bursts in the data collected by the LIGO, GEO 600 and Virgo detectors between November 2006 and October 2…
Virgo calibration and reconstruction of the gravitational wave strain during VSR1
The Virgo collaboration, T. Accadia, F. Acernese +171
Virgo is a kilometer-length interferometer for gravitational waves detection located near Pisa. Its first science run, VSR1, occured from May to October 2007. The aims of the calib…
Comparing scalar-tensor gravity and f(R)-gravity in the Newtonian limit
S. Capozziello, A. Stabile, A. Troisi
Recently, a strong debate has been pursued about the Newtonian limit (i.e. small velocity and weak field) of fourth order gravity models. According to some authors, the Newtonian l…
Neutrino oscillation phase dynamically induced by f(R)-gravity
S. Capozziello, M. De Laurentis, D. Vernieri
The gravitational phase shift of neutrino oscillation can be discussed in the framework of f(R)-gravity. We show that the shift of quantum mechanical phase can depend on the given…
The post-Minkowskian limit of f(R)-gravity
S. Capozziello, A. Stabile, A. Troisi
We formally discuss the post-Minkowskian limit of -gravity without adopting conformal transformations but developing all the calculations in the original Jordan frame. It is…
