Schwarzschild Spacetime and the Local Limit of Nonlocal Gravity
Yahya Mohammadi, Javad Tabatabaei, Shant Baghram +1
We investigate static spherically symmetric solutions within the framework of the local limit of nonlocal gravity. This theory departs from Einstein's general relativity (GR) throu…
Elliptically Polarized Plane Gravitational Waves
Masoud Molaei, Shant Baghram, Bahram Mashhoon
Exact plane gravitational radiation fields are presented within the framework of general relativity and their properties are described. The physics of nonlinear elliptically polari…
Local Peculiar Motions in McVittie and LTB Spacetimes
Masoud Molaei, Shant Baghram, Bahram Mashhoon
We consider two inhomogeneous cosmological models, namely, the flat McVittie spacetime and a simple specific LTB spacetime. Relative to the world line of a reference comoving obser…
McVittie-Plummer Spacetime: Plummer Sphere Immersed in the FLRW Universe
Javad Tabatabaei, Shant Baghram, Bahram Mashhoon
The McVittie-Plummer spacetime is a spherically symmetric inhomogeneous cosmological model that represents a spherical star system embedded in a standard FLRW cosmological model. W…
Local Limit of Nonlocal Gravity: A Teleparallel Extension of General Relativity
Javad Tabatabaei, Shant Baghram, Bahram Mashhoon
We describe a general constitutive framework for a teleparallel extension of the general theory of relativity. This approach goes beyond the teleparallel equivalent of general rela…
