Statefinder Analysis of f(T) Cosmology
Mubasher Jamil, Davood Momeni, Ratbay Myrzakulov +1
In this paper, we intend to evaluate and analyze the statefinder parameters in cosmology. Friedmann equation in model is taken, and the statefinder parameters …
Observational Constraints of Homogeneous Higher Dimensional Cosmology with Modified Chaplygin Gas
Chayan Ranjit, Shuvendu Chakraborty, Ujjal Debnath
In this work, we have considered the flat FRW model of the universe in -dimensions filled with the dark matter (perfect fluid with negligible pressure) and the modified Chap…
Observational Constraints of Modified Chaplygin Gas in Loop Quantum Cosmology
Shuvendu Chakraborty, Ujjal Debnath, Chayan Ranjit
We have considered the FRW universe in loop quantum cosmology (LQC) model filled with the dark matter (perfect fluid with negligible pressure) and the modified Chaplygin gas (MCG)…
Dynamics of Interacting Generalized Cosmic Chaplygin gas in Brane-world scenario
Prabir Rudra
In this work we explore the background dynamics when dark energy is coupled to dark matter with a suitable interaction in the universe described by brane cosmology. Here DGP and th…
Monthly sunspot number time series analysis and its modeling through autoregressive artificial neural network
Goutami Chattopadhyay, Surajit Chattopadhyay
This study reports a statistical analysis of monthly sunspot number time series and observes non homogeneity and asymmetry within it. Using Mann-Kendall test a linear trend is reve…
Interacting Generalised Cosmic Chaplygin gas in Loop quantum cosmology: A singularity free universe
Ratul Chowdhury, Prabir Rudra
In this work we investigate the background dynamics when dark energy is coupled to dark matter with a suitable interaction in the universe described by Loop quantum cosmology. Dark…
