Was There a Decelerating Past for the Universe?
Moncy V. John
In this talk, I argue that the method of analysing the m-z data of Type Ia Supernovae (SNe Ia) by assuming exotic energy densities with strange equations of state is misleading and…
Cosmography, Decelerating Past, and Cosmological Models: Learning the Bayesian Way
Moncy V. John
In this paper, using a significantly improved version of the model-independent, cosmographic approach to cosmology (John, M. V. 2004, ApJ, 614, 1), we address an important question…
Cosmographic evaluation of deceleration parameter using SNe Ia data
Moncy V. John
The apparent magnitude-redshift data of SNe Ia call for modifications in the standard model energy densities. Under the circumstance that this modification cannot be limited to the…
Classical stochastic approach to cosmology revisited
Moncy V. John, C. Sivakumar, K. Babu Joseph
The classical stochastic model of cosmology recently developed by us is reconsidered. In that approach the parameter defined by the equation of state was taken to be flu…
Stochastic evolution of cosmological parameters in the early universe
C. Sivakumar, Moncy V. John, K. Babu Joseph
We develop a stochastic formulation of cosmology in the early universe, after considering the scatter in the redshift-apparent magnitude diagram in the early epochs as an observati…
Comparison of cosmological models using Bayesian theory
Moncy V. John, J. V. Narlikar
Using the Bayesian theory of model comparison, a new cosmological model due to John and Joseph [M. V. John and K. Babu Joseph, Phys. Rev. D 61, 87304 (2000)] is compared with the s…
