How much a galaxy knows about its large-scale environment?: An information theoretic perspective
Biswajit Pandey, Suman Sarkar
The small-scale environment characterized by the local density is known to play a crucial role in deciding the galaxy properties but the role of large-scale environment on galaxy f…
The many scales to cosmic homogeneity: Use of multiple tracers from the SDSS
Prakash Sarkar, Subhabrata Majumdar, Biswajit Pandey +2
We carry out multifractal analyses of multiple tracers namely the main galaxy sample, the LRG sample and the quasar sample from the SDSS to test the assumption of cosmic homogeneit…
An information theory based search for homogeneity on the largest accessible scale
Suman Sarkar, Biswajit Pandey
We analyze the SDSS DR12 quasar catalogue to test the large-scale smoothness in the quasar distribution. We quantify the degree of inhomogeneity in the quasar distribution using in…
Relating information entropy and mass variance to measure bias and non-Gaussianity
Biswajit Pandey
We relate the information entropy and the mass variance of any distribution in the regime of small fluctuations. We use a set of Monte Carlo simulations of different homogeneous an…
