Gravitational Lensing by a structure in a cosmological background
M. Parsi Mood, Javad T. Firouzjaee, Reza Mansouri
We use an exact general relativistic model structure within an FRW cosmological background based on a LTB metric to study the gravitational lensing by a cosmological and dynamical…
Comment on "Inflation with a graceful exit and entrance driven by Hawking radiation"
Javad T. Firouzjaee
Modak and Singleton [Phys. Rev. D 86, 123515 (2012)] have presented Hawking-like radiation for cosmological inflation which has a natural "turn on" and a natural "turn off" mechani…
Exact general relativistic lensing versus thin lens approximation: the crucial role of the void
M. Parsi Mood, Javad T. Firouzjaee, Reza Mansouri
We have used an exact general relativistic model structure within a FRW cosmological background based on a LTB metric to study the gravitational lensing of a cosmological structure…
δN Formalism in Anisotropic Inflation and Large Anisotropic Bispectrum and Trispectrum
Ali Akbar Abolhasani, Razieh Emami, Javad T. Firouzjaee +1
We present a consistent δN formalism for curvature perturbations in anisotropic cosmological backgrounds. We employ our δN formalism to calculate the power spectrum, the bispectrum…
The holographic bound in the scalar-tensor and gravities
J. T. Firouzjaee
The holographic bound has been extended to the different theory of gravities such as scalar-tensor gravity and gravity according to the Noether charge definition of the entr…
The spherical perfect fluid collapse with pressure in the cosmological background
Rahim Moradi, Javad T. Firouzjaee, Reza Mansouri
We have constructed a spherically symmetric structure model in a cosmological background filled with perfect fluid with non-vanishing pressure and studied its quasi-local character…
