We study gravitational collapse of a charged black hole in f(R) gravity using double-null formalism. We require cosmological stability to f(R) models; we used the Starobinsky model and the R+(1/2)cR2 model. Charged black holes in f(R) gravity can have a new type of singularity due to higher curvature corrections, the so-called f(R)-induced singularity, although it is highly model-dependent. As the advanced time increases, the internal structure will approach the Cauchy horizon, which may not be… 
Higher-dimensional inhomogeneous perfect fluid collapse in f(R) gravity
This paper is about the $$n+2$$n+2-dimensional gravitational contraction of an inhomogeneous fluid without heat flux in the framework of a f(R) metric theory of gravity. Matching conditions for two
Gravitational collapse of massless scalar field in $f(R)$ gravity
We study the spherically symmetric gravitational collapse of massless scalar matter field in asymptotic flat spacetime in the Starobinsky ${R}^{2}$ gravity, one specific model in the $f(R)$ gravity.
One-loop modified gravity in a de Sitter universe, quantum-corrected inflation, and its confrontation with the Planck result
Motivated by issues on inflation, a generalized modified gravity model is investigated, where the model Lagrangian is described by a smooth function $f(R, K, \phi)$ of the Ricci scalar $R$, the
J Cusp singularities in f ( R ) gravity : pros and cons
We investigate cusp singularities in f(R) gravity, especially for Starobinsky and Hu-Sawicki dark energy models. We illustrate that, by using double-null numerical simulations, a cusp singularity can
Interior Dynamics of Neutral and Charged Black Holes in f(R) Gravity
In this paper, we explore the interior dynamics of neutral and charged black holes in f(R) gravity. We transform f(R) gravity from the Jordan frame into the Einstein frame and simulate scalar
Spherical vacuum and scalar collapse for the Starobinsky $R^2$ model
Spherical vacuum and scalar collapse for the Starobinsky R^2 model is simulated. Obtained by considering the quantum-gravitational effects, this model would admit some cases of singularity-free
f(R) Gravity and Spherical Collapse
This thesis studies f(R) model building, cosmological dynamics, Solar System tests of f(R) gravity, and spherical collapse in f(R) gravity. We apply the running coupling idea to gravity. We describe
Cusp singularities in f(R) gravity: pros and cons
We investigate cusp singularities in f(R) gravity, especially for Starobinsky and Hu-Sawicki dark energy models. We illustrate that, by using double-null numerical simulations, a cusp singularity can
Trace-anomaly driven inflation in modified gravity and the BICEP2 result
We explore conformal-anomaly driven inflation in $F(R)$ gravity without invoking the scalar-tensor representation. We derive the stress-energy tensor of the quantum anomaly in the flat homogeneous
Gravitational collapse involving electric charge in the decoupling limit of the dilatonic Gauss--Bonnet gravity
The paper presents the course and outcomes of gravitational collapse of a selfinteracting electrically charged scalar field in the decoupling limit of the dilatonic Gauss– Bonnet gravity. The


Disappearing cosmological constant in f(R) gravity
For higher-derivative f(R) gravity, where R is the Ricci scalar, a class of models is proposed, which produce viable cosmology different from the ACDM at recent times and satisfy cosmological, Solar
Mass Inflation in the Loop Black Hole
In classical general relativity the Cauchy horizon within a two-horizon black hole is unstable via a phenomenon known as mass inflation, in which the mass parameter (and the spacetime curvature) of
Mass Inflation in Brans-Dicke gravity
A detailed nonlinear analysis of the internal structure of spherical, charged black holes that are accreting scalar matter is performed in the framework of the Brans-Dicke theory of gravity. We
We review various modified gravities considered as gravitational alternative for dark energy. Specifically, we consider the versions of f(R), f(G) or f(R, G) gravity, model with non-linear
The causal structure of dynamical charged black holes
We study the causal structure of dynamical charged black holes, with a sufficient number of massless fields, using numerical simulations. Neglecting Hawking radiation, the inner horizon is a null

The gravitational effects associated with the radiative tail produced by a gravitational collapse with rotation are investigated. It is shown that the infinite blueshift of the tail's energy density
Dynamical formation and evolution of (2+1)-dimensional charged black holes
In this paper, we investigate the dynamical formation and evolution of 2 + 1-dimensional charged black holes. We numerically study dynamical collapses of charged matter fields in an anti de Sitter
Physical equivalence between nonlinear gravity theories and a general-relativistic self-gravitating scalar field.
The global net of relationships between the nonlinear gravity theories, scalar-tensor theories, and general relativity is clarified, showing that in a sense these are ``canonically conjugated'' to each other.
The Large Scale Structure of Space-Time
The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions.
Black holes as possible sources of closed and semiclosed worlds.
It is shown that instead of the singularity the closed world can be formed inside the black hole and it is argued that this property of this model may also be valid in a more general case provided the gravitation theory is asymptotically free and the limiting curvature exists.
