Analysis of fractional Gaussian noises using level crossing method
M. Vahabi, G. R. Jafari, M. Sadegh Movahed
The so-called level crossing analysis has been used to investigate the empirical data set. But there is a lack of interpretation for what is reflected by the level crossing results…
Observational Constraints on the Normal Branch of a Warped DGP Cosmology
T. Azizi, M. Sadegh Movahed, Kourosh Nozari
We investigate observational constraints on the normal branch of the warped DGP braneworld cosmology by using observational data from Type Ia Supernovae (SNIa), Baryon Acoustic Osc…
Geometrical exponents of contour loops on synthetic multifractal rough surfaces: multiplicative hierarchical cascade p-model
S. Hosseinabadi, M. A. Rajabpour, M. Sadegh Movahed +1
In this paper, we study many geometrical properties of contour loops to characterize the morphology of synthetic multifractal rough surfaces, which are generated by multiplicative…
Tachyon Reconstruction of Ghost Dark Energy
A. Sheykhi, M. Sadegh Movahed, E. Ebrahimi
Recently it has been argued that a possible source for the dark energy may arise due to the contribution to the vacuum energy of the QCD ghost in a time-dependent background. In th…
Interacting Ghost Dark Energy in Non-Flat Universe
A. Sheykhi, M. Sadegh Movahed
A new dark energy model called "ghost dark energy" was recently suggested to explain the observed accelerating expansion of the universe. This model originates from the Veneziano g…
