We use information entropy to analyse the anisotropy in the mock galaxy catalogues from dark matter distribution and simulated biased galaxy distributions from cold dark matter N-body simulation. We show that one can ...

We study the evolution of the configuration entropy of HI distribution in the post-reionization era assuming different time evolution of HI bias. We describe time evolution of linear bias of HI distribution using a simple ...

We use an information theoretic framework to analyse data from the Galaxy Zoo 2 project and study if there are any statistically significant correlations between the presence of bars in spiral galaxies and their environment. ...

We analyse a set of volume-limited samples from the Sloan Digital Sky Survey (SDSS) to study the dependence of galaxy colour on different environments of the cosmic web. We measure the local dimension of galaxies to ...

We analyse the Sloan Digital Sky Survey Data Release 12 quasar catalogue to test the large scale smoothness in the quasar distribution. We quantify the degree of inhomogeneity in the quasar distribution using information ...

We propose a method for testing isotropy of a three-dimensional distribution using Shannon entropy. We test the method on some Monte Carlo simulations of isotropic and anisotropic distributions and find that the method ...

We quantify the degree of inhomogeneity in the Luminous Red Galaxy (LRG) distribution from the SDSS DR7 as a function of length scales by measuring the Shannon entropy in independent and regular cubic voxels of increasing ...

We propose a method for testing homogeneity in three dimensional spatial dis tributions using Renyi entropy. We apply the proposed method to data from cosmological N-body simulations and Monte Carlo simulations of homogeneous ...

We analyse a volume-limited galaxy sample from the Sloan Digital Sky Survey (SDSS) in order to study the environments of galaxies on different length-scales in the local Universe. We measure the local dimension of the ...
