By a representative set of hydrodynamical simulations we investigate the influence of the high-density equation of state on observable features of neutron-star mergers. The dependence of the gravitational-wave emission on the equation of state of neutron-star matter is addressed. On the basis of our survey we point out a novel possibility to determine neutron-star radii from gravitational-wave...

A spinning neutron star, if asymmetric respect to the rotation axis, is expected to emit a continuous gravitational wave signal. In this talk I present a summary of the results obtained in the analysis of LIGO and Virgo data searching for continuous gravitational wave signals emitted by known pulsars. I focus attention on the astrophysical interpretation of the most interesting upper limits...

We present the basic equations and relations for the relativistic static spherically symmetric stars (SSSS) in the model of minimal dilatonic gravity (MDG) which is locally equivalent to the f(R) theories of gravity and gives an alternative description of the effects of dark matter and dark energy. The results for a simplest form of relativistic equation of state (EOS) of neutron...

High-time-resolution and spectroscopic X-ray observations of compact objects provide access to strong-field gravity, the equation of state of ultra-dense matter and black hole masses and spins. A 10 m^2-class instrument in combination with good energy resolution is required to exploit diagnostics and answer two of the fundamental questions of the European Space Agency (ESA) Cosmic Vision...

The gravitational signal emitted in the late inspiral of a binary system, composed by a neutron star and another compact object, encodes the deformability properties of the neutron star, which depend on the behaviour of matter in the stellar interior. We discuss how the detection of this signal from ground based interferometers of second and third generation, can be used to extract information...

Fisher matrix and related studies have suggested that with second-generation gravitational wave detectors, it may be possible to infer the equation of state of neutron stars using tidal effects in binary inspiral. Here we present the first fully Bayesian investigation of this problem. We simulate a realistic data analysis setting by performing a series of numerical experiments of binary...
