We discuss the future of gravitational theories in the framework of gravitational wave (GW) astronomy after the recent GW detections (the events GW150914, GW151226, GW170104, GW170814, GW170817 and GW170608). In particular, a calculation of the frequency and angular dependent response function that a GW detector would see if massive modes from f(R) theories or scalar–tensor gravity (STG) were present, allowing for sources incident from any direction on the sky, is shown. In addition, through…

Constraint on reconstructed f(R) gravity models from gravitational waves

The gravitational wave (GW) detection of a binary neutron star inspiral made by the Advanced LIGO and Advanced Virgo paves the unprecedented way for multi-messenger observations. The propagation

Laser interferometer in presence of scalar field on gravitational wave background

Detection of gravitational waves opened new windows on fundamental physics and it would be natural to search how the role of extra dimensional effects can be traced to gravitational wave physics. In

Non-Detection of Dark Matter Particles: A Case for Alternate Theories of Gravity

While there is overwhelming evidence for dark matter (DM) in galaxies and galaxy clusters, all searches for DM particles have so far proved negative. It is not even clear whether only one particle is

Astrophysical Constraints on Strong Modified Gravity

We offer a discussion on the strong field regime predictions of two families of theories that deviate from General Relativity in different aspects: $f(R)$-gravity and Scalar-Tensor-Vector Gravity

Developments of the Relativistic Bohm-Poisson Equation and Dark Energy

The nonlinear and novel Bohm-Poisson-Schrödinger equation proposed by us is studied further. It has solutions leading to repulsive gravitational behavior. An exact analytical expression for the

Dynamics of Bianchi I Universe in Extended Gravity with Scale Factors

In this paper, the dynamical behavior of an anisotropic universe in an extended gravity e.g. the f (R,T ) theory of gravity is studied. We use f (R,T ) = R + 2μT , where R is the Ricci scalar, T is

A note on cosmological features of modified Newtonian potentials

Considering some modified Newtonian potentials and the Hubble law in writing the total energy of a test mass located at the edge of a flat Friedmann–Robertson–Walker (FRW) universe, we obtain several

MONG: An extension to Galaxy Clusters

The presence of dark matter, though well established by indirect evidence is yet to be observed directly. Various dark matter detection experiments running for several years have yielded no positive

Effect of Quantum Gravity on the Stability of Black Holes

The tunneling mechanism of charged bosons from the gauged super-gravity black hole is observed and the appropriate radiation consistent with black holes can be obtained under the condition that back reaction of the emitted charged particle with self-gravitational interaction is neglected.



Gravitational Waves from the Collapse and Bounce of a Stellar Core in Tensor-Scalar Gravity

Tensor-scalar theory of gravity allows the generation of gravitational waves from astrophysical sources, like supernovae, even in the spherical case. That motivated us to study the collapse of a

Interferometric Detection of Gravitational Waves:. the Definitive Test for General Relativity

Even though Einstein's general relativity has achieved great success and passed a lot of experimental tests, it has also shown some shortcomings and flaws which today prompt theorists to ask if it is

Precise response function for the magnetic component of gravitational waves in scalar-tensor gravity

The important issue of the magnetic component of gravitational waves (GWs) has been considered in various papers in the literature. From such analyses, it has been found that such a magnetic

Response of test masses to gravitational waves in the local lorentz gauge

The local Lorentz gauge represents a natural coordinate frame for an observer to analyze the effect of gravitational waves on detectors, and has been widely used to describe the response of resonant

Gravitational-Wave Tests of General Relativity with Ground-Based Detectors and Pulsar-Timing Arrays

This review is focused on tests of Einstein’s theory of general relativity with gravitational waves that are detectable by ground-based interferometers and pulsar-timing experiments, and the predicted gravitational-wave observables of modified gravity theories.

GW151226: Observation of Gravitational Waves from a 22-Solar-Mass Binary Black Hole Coalescence.

This second gravitational-wave observation provides improved constraints on stellar populations and on deviations from general relativity.

Tests of General Relativity with GW150914.

It is found that the final remnant's mass and spin, as determined from the low-frequency and high-frequency phases of the signal, are mutually consistent with the binary black-hole solution in general relativity.
