Shadows and photon rings of a spherically accreting Kehagias-Sfetsos black hole
Mohaddese Heydari-Fard, Malihe Heydari-Fard, Nematollah Riazi
By considering Kehagias-Sfetsos black hole in the framework of the Hořava-Lifshitz gravity, we study the optical appearance of such black holes surrounded by spherical accretion fl…
Dynamics of kink train solutions in deformed Multiple sine-Gordon models
Marzieh Peyravi, Nematollah Riazi, Kurosh Javidan
This paper examines the effects of a thin layer of inhomogeneity on periodic solutions of the Multiple-sine-Gordon (MsG) model. We investigate the dynamics of the perturbed Double-…
Fluid Dynamical Description of Sine-Gordon Solitons
Nematollah Riazi, Marzieh Peyravi
We present a fluid dynamical description of a relativistic scalar field in dimensions and apply the general results to the special case of Sine-Gordon solitons. The results w…
Quantum Cosmology in Thick Brane
S. H. Hendi, N. Riazi, S. N. Sajadi
One of the interesting open problems in the cosmological framework is applying quantum physics to the whole universe, consistently. Although different conceptual aspects of quantum…
A note on inflation in dRGT massive gravity
B. Afshar, N. Riazi, H. Moradpour
Although the dRGT massive gravity successfully explains the late-time cosmic acceleration, it cannot justify inflation. On the other hand, and in the frameworks of General Relativi…
Analytically Approximation Solution to Higher Derivative Gravity
S. N. Sajadi, Robert B. Mann, N. Riazi +1
We obtain analytical approximate black hole solutions for higher derivative gravity in the presence of Maxwell electromagnetic source. We construct near horizon and asymptotic solu…
