The local environment of flat galaxies
Suman Sarkar, Arunima Banerjee, Dmitry Makarov
The existence of flat or bulgeless galaxies poses a challenge to the hierarchical structure formation scenario advocated by modern cosmology. We determine the geometrical environme…
Galaxy interactions in different environments: An analysis of galaxy pairs from the SDSS
Apashanka Das, Biswajit Pandey, Suman Sarkar +1
We analyze the galaxy pairs in a volume limited sample () from the SDSS to study the effects of galaxy interactions on the star formation rate and colour of galaxies…
Testing homogeneity of the galaxy distribution in the SDSS using Renyi entropy
Biswajit Pandey, Suman Sarkar
We analyze a set of volume limited sample of galaxies from the SDSS to study the issue of cosmic homogeneity. We use the Renyi entropy of different order to probe the inhomogenetie…
Green valley galaxies in the cosmic web: internal versus environmental quenching
Apashanka Das, Biswajit Pandey, Suman Sarkar
We analyze the SDSS data to classify the galaxies based on their colour using a fuzzy set-theoretic method and quantify their environments using the local dimension. We find that t…
Do galactic bars depend on environment?: An information theoretic analysis of Galaxy Zoo 2
Suman Sarkar, Biswajit Pandey, Snehasish Bhattacharjee
We use an information theoretic framework to analyze data from the Galaxy Zoo 2 project and study if there are any statistically significant correlations between the presence of ba…
Can a conditioning on stellar mass explain the mutual information between morphology and environment?
Snehasish Bhattacharjee, Biswajit Pandey, Suman Sarkar
Recent studies with SDSS have shown that a statistically significant non-zero mutual information between morphology and environment persists up to several tens of Mpc, which awaits…
