The Brans-Dicke theory of gravity is one of the oldest ideas to extend general relativity by introducing a non-minimal coupling between the scalar field and gravity. The Solar System tests put tight constraints on the theory. In order to evade these constraints, various screening mechanisms have been proposed. These screening mechanisms allow the scalar field to couple to matter as strongly as gravity in low density environments while suppressing it in the Solar System. The Vainshtein mechanism…

Anisotropic stars in Brans-Dicke gravity
Abstract In the present work we show application of Brans-Dicke theory of gravitation, as an alternative to Einstein’s general relativity, in modeling anisotropic compact stellar objects. To make the
Difficulties in reconciling non-negligible differences between the local and cosmological values of the gravitational coupling in extended Brans-Dicke theories
Recent studies by Solà Peracaula, Gómez-Valent, de Cruz Pérez and Moreno-Pulido (2019,2020) have pointed out the intriguing possibility that Brans-Dicke cosmology with constant vacuum energy density
Framework for describing perturbations to the cosmic microwave background from a gravitational wave burst with memory
Gravitational wave bursts with memory (BWMs) can generate measurable, long-lived frequency shifts and permanent angular deflections in distant sources of light. These perturbations vary across the
Gravitational breathing memory and dual symmetries
Brans-Dicke theory contains an additional propagating mode which causes homogeneous expansion and contraction of test bodies in transverse directions. This “breathing” mode is associated with novel
Gravitational memory effects in Chern-Simons modified gravity
The gravitational memory effects of Chern-Simons modified gravity are considered in the asymptotically flat spacetime. If the Chern-Simons scalar does not directly couple with the ordinary matter
Gravitational-wave memory effects in Brans-Dicke theory: Waveforms and effects in the post-Newtonian approximation
Gravitational-wave (GW) memory effects produce permanent shifts in the GW strain and its time integrals after the passage of a burst of GWs. Their presence is closely tied to the symmetries of
Kundt geometries and memory effects in the Brans–Dicke theory of gravity
Memory effects are studied in the simplest scalar–tensor theory, the Brans–Dicke (BD) theory. To this end, we introduce, in BD theory, novel Kundt spacetimes (without and with gyratonic terms), which
Constraining scalar-tensor modified gravity with gravitational waves and large scale structure surveys
The first multi-messenger gravitational wave event has had a transformative effect on the space of modified gravity models. In this paper we study the enhanced tests of gravity that are possible with
Gravitational memory effects and Bondi-Metzner-Sachs symmetries in scalar-tensor theories
The relation between gravitational memory effects and Bondi-Metzner-Sachs symmetries of the asymptotically flat spacetimes is studied in the scalar-tensor theory. For this purpose, the solutions to


Gravitational wave memory: A new approach to study modified gravity
It is well known that two types of gravitational wave memory exist in general relativity (GR): the linear memory and the nonlinear, or Christodoulou, memory. These effects, especially the latter,

Equivalence Principle Implications of Modified Gravity Models
Theories that attempt to explain the observed cosmic acceleration by modifying general relativity all introduce a new scalar degree of freedom that is active on large scales, but is screened on small
Relativistic stars in a cubic Galileon universe
We study relativistic stars in Hordenski theories that evade the gravitational wave constraints and exhibit the Vainshtein mechanism, focusing on a model based on the cubic Galileon Lagrangian. We

The detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an opportunity to test general relativity in a regime that is inaccessible to traditional astronomical observations
Erratum: Tests of General Relativity with GW150914 [Phys. Rev. Lett. 116, 221101 (2016)].
This corrects the article DOI: 10.1103/PhysRevLett.116.221101 to reflect that the paper was originally published in Physical Review Letters, not RevLett, rather than Science.

Tests of Gravity Theories Using Supermassive Black Holes
Scalar-tensor theories of gravity generally violate the strong equivalence principle, namely compact objects have a suppressed coupling to the scalar force, causing them to fall slower. A black hole
