Lambda Cold Dark Matter cosmological model of the Universe Lambda CDM In 1995, astronomers using the Hubble telescope solved a 20-year-old mystery by showing a class of galaxies once thought to be rare is actually the most common type of galaxy in the universe. ...
A Bianchi type II cosmological model with expansion and rotation has been constructed. The model describes the Friedmannian stage of the Universe's evolution including a subsequent transition to the accelerated exponential expansion observed nowadays. The gravitational field sources of the model are an ...

Kaluza-Klein theory of gravitationVariable ΛViscous fluidIn this paper we have investigated Kaluza-Klein type 5–dimensional model of universe with a flat geometry filled with viscous fluid in the presence of variable cosmological term Λ. A non-singular solution leading to a variable deceleration ...
In this paper, we obtain a spatially homogeneous and anisotropic Bianchi type-V cosmological model of the universe for perfect fluid distribution with heat flow within the framework of scalar-tensor theory of gravitation proposed by Saez and Ballester (Phys. Lett. 113:467, 1986). To prevail the...
We obtain exact solutions of Einstein's field equations using the condition that the shear scalar is proportional to the expansion scalar, which represent singular and non-singular cosmological models of the universe. The physical behavior of the models are discussed. We conclude that the universe ...
We consider different models of accelerating Universe which describe the current evolution of the Universe. We demonstrate that the generalized Akaike criterion (Bozdogen criterion) distinguishes the very simple standard cosmological model called LCDM (Lamda Cold Dark Matter model...
The exact solutions of the field equations are obtained, which represent an expanding model of the universe which starts expanding with a big bang at \( t = 0\) . The physical behaviours of the model are discussed. 展开 关键词: Cosmological Model Deceleration Parameter Cosmic Time Stress ...
