Search for anomalous alignments of structures in Planck data using Minkowski Tensors
Joby P. K., Pravabati Chingangbam, Tuhin Ghosh +2
Minkowski Tensors are tensorial generalizations of the scalar Minkowski Functionals. Due to their tensorial nature they contain additional morphological information of structures,…
Minkowski Tensors in Two Dimensions - Probing the Morphology and Isotropy of the Matter and Galaxy Density Fields
Stephen Appleby, Pravabati Chingangbam, Changbom Park +3
We apply the Minkowski Tensor statistics to two dimensional slices of the three dimensional density field. The Minkowski Tensors are a set of functions that are sensitive to direct…
Tensor Minkowski Functionals for random fields on the sphere
Pravabati Chingangbam, K P Yogendran, Joby P. K. +3
We generalize the translation invariant tensor-valued Minkowski Functionals which are defined on two-dimensional flat space to the unit sphere. We apply them to level sets of rando…
On Minkowski Functionals of CMB polarization
Pravabati Chingangbam, Vidhya Ganesan, K. P. Yogendran +1
CMB polarization data is usually analyzed using and modes because they are scalars quantities under rotations along the lines of sight and have distinct physical origins. W…
Tensor Minkowski Functionals: first application to the CMB
Vidhya Ganesan, Pravabati Chingangbam
Tensor Minkowski Functionals (TMFs) are tensorial generalizations of the usual Minkowski Functionals which are scalar quantities. We introduce them here for use in cosmological ana…
Primordial non-Gaussian signatures in CMB polarization
Vidhya Ganesan, Pravabati Chingangbam, K. P. Yogendran +1
We study the signatures of local type primordial non-Gaussianity, parametrized by $\fnl$, of scalar perturbations in CMB polarization using the probability distribution functions,…
