MOG cosmology without dark matter and the cosmological constant
  In this work, we investigate the MOdified Gravity (MOG) theory for dynamics
of the universe and compare the results with the $\Lambda$CDM cosmology. We
study the background cosmological properties of the MOG model and structure
formation at the linear perturbation level. We compare the two models with the
currently available cosmological data by using statistical Bayesian analyses.
After obtaining updated constraints on the free parameters, we use some methods
of model selection to assist in choosing the more consistent model such as the
reduced chi-squared ($\chi^2_{\rm red}$) and a number of the basic information
criteria such as the Akaike Information Criterion (AIC), the Bayes factor or
Bayesian Information Criterion (BIC), and Deviance Information Criterion (DIC).
MOG model appears to be consistent with the $\Lambda$CDM model by the results
of $\chi^2_{\rm red}$ and DIC for an overall statistical analysis using the
background data and the linear growth of structure formation.
