Test of cosmic isotropy in the Planck era
Yabebal Fantaye
The two fundamental assumptions in cosmology are that the Universe is statistically homogeneous and isotropic when averaged on large scales. Given the big implication of these assu…
A Simple Proposal for Radial 3D Needlets
Claudio Durastanti, Yabebal T. Fantaye, Frode K. Hansen +2
We present here a simple construction of a wavelet system for the three-dimensional ball, which we label \emph{Radial 3D Needlets}. The construction envisages a data collection env…
Cosmological Applications of the Gaussian Kinematic Formula
Yabebal Fantaye, Frode Hansen, Davide Maino +1
The Gaussian Kinematic Formula (GKF, see Adler and Taylor (2007,2011)) is an extremely powerful tool allowing for explicit analytic predictions of expected values of Minkowski func…
