Clustering of eclipsing binary light curves through functional principal component analysis
Soumita Modak, Tanuka Chattopadhyay, Asis Kumar Chattopadhyay
In this paper, we revisit the problem of clustering 1318 new variable stars found in the Milky way. Our recent work distinguishes these stars based on their light curves which are…
Clustering of Gamma-Ray bursts through kernel principal component analysis
Soumita Modak, Asis Kumar Chattopadhyay, Tanuka Chattopadhyay
We consider the problem related to clustering of gamma-ray bursts (from "BATSE" catalogue) through kernel principal component analysis in which our proposed kernel outperforms resu…
Use of spatial cross correlation function to study formation mechanism of massive elliptical galaxies
Tuli De, Tanuka Chattopadhyay, Asis Kumar Chattopadhyay
Spatial clustering nature of galaxies have been studied previously through auto correlation function. The same type of cross correlation function has been used to investigate param…
