Inflation based on the Tsallis entropy

open access: yesEuropean Physical Journal C: Particles and Fields
We study the inflationary scenario in the Tsallis entropy-based cosmology. The Friedmann equations in this setup can be derived by using the first law of thermodynamics.

Large-Angle Anomalies in the CMB

open access: yesAdvances in Astronomy, 2010
We review the recently found large-scale anomalies in the maps of temperature anisotropies in the cosmic microwave background. These include alignments of the largest modes of CMB anisotropy with each other and with geometry and direction of motion of ...

Is Planckian Discreteness Observable in Cosmology?

open access: yesUniverse
A Planck scale inflationary era—in a quantum gravity theory predicting discreteness of quantum geometry at the fundamental scale—produces the scale-invariant spectrum of inhomogeneities with a very small tensor-to-scalar ratio of perturbations and a hot ...
