Consistency Conditions and the Derivation of Harmonic Structure in Einstein-Maxwell-dilaton Theory
Bardia H. Fahim, Joshua G. Fenwick
Many exact solutions of Einstein-Maxwell and Einstein-Maxwell-dilaton theory share a common structural pattern in which the metric functions are built from harmonic functions on a…
Exact Dynamical Black Hole Solutions in Five or Higher Dimensions
B. H. Fahim, A. M. Ghezelbash
We construct new classes of the dynamical black hole solutions in five or higher dimensional Einstein-Maxwell theory, coupled to a dilaton field, in the presence of arbitrary cosmo…
Generalized Hidden Conformal Symmetry in Quadratic Gravity
B. H. Fahim, A. M. Ghezelbash
We find the non-extremal charged rotating black holes in quadratic gravity are holographically dual to two different hidden conformal field theories. The two conformal field…
New Rotating Black Hole Solutions With Imperfect Fluid Energy-Momentum Tensor In Gravity
B. H. Fahim, A. M. Ghezelbash
We find a new class of exact solutions for rotating black holes in gravity in presence of imperfect fluid. We find that the exact solutions are holographically dual to a hid…
New class of exact solutions to Einstein-Maxwell-dilaton theory on four-dimensional Bianchi type IX geometry
Bardia H. Fahim, Masoud Ghezelbash
We construct new classes of cosmological solution to the five dimensional Einstein-Maxwell-dilaton theory, that are non-stationary and almost conformally regular everywhere. The ba…
Spherical inhomogeneous solutions of Einstein and scalar-tensor gravity: a map of the land
Valerio Faraoni, Andrea Giusti, Bardia H. Fahim
We review spherical and inhomogeneous analytic solutions of the field equations of Einstein and of scalar-tensor gravity, including Brans-Dicke theory, non-minimally (possibly conf…
Emmy's letter to Santa Claus (and a reply): Vaidya geometries and scalar fields with null gradients
Valerio Faraoni, Andrea Giusti, Bardia H. Fahim
Emmy, a child prodigy, writes a letter to Santa Claus asking for a Vaidya solution sourced by a massless scalar field with null gradient for Christmas. Santa writes back explaining…
Brans-Dicke analogue of the Roberts geometry
Bardia H. Fahim, Valerio Faraoni, Andrea Giusti
We report a new one-parameter family of spherically symmetric, inhomogeneous, and time-dependent solutions of the vacuum Brans-Dicke field equations which are conformal to the Robe…
