Recent detections of gravitational waves, together with the increasing precision of electromagnetic observations of neutron stars and black holes, have expanded the possibility of testing the theory of General Relativity. ...

In this work, the gravitational radiation emitted from a compact binary system is analyzed in the context of general relativity and f(R) gravity based on linearized theory. Besides the two standard polarizations of ...

A simple and scalable procedure was used to obtain thin, stable, homogeneous, and easy-to-handle films composed of silicone derived from dimethicones containing dispersed hydrotalcite-type materials previously organo-modified ...

© 2019 IOP Publishing Ltd and Sissa Medialab.The extended Jordan-Brans-Dicke (eJBD) theory of gravity is constrained by a host of astrophysical and cosmological observations spanning a wide range of scales. The current ...

Modified Newtonian Dynamics (MoND) is an empirically modification of Newtonian gravity at largest scales in order to explain rotation curves of galaxies, as an alternative to nonbaryonic dark matter. But MoND theories can ...

Fourth Order gravity theory, discussed by S. Banerjee, S. Vera and T. Singh (2017), is the gravity theory presented in this work. This model is applied to the problem example of the gravitational waves produced by a binary ...

In the weak field approximation of higher order gravity theory a gravitational potential is described by a Newtonian plus a Yukawa-like term. This new term is used to explain some aspects of galactic dynamics, without ...

Mapping the dark matter distribution across our Galaxy represents a central challenge for the near future as a new generation of space-borne and ground-based astronomical surveys swiftly comes online. Here we present a ...
