Cosmic history of integrated galactic stellar initial mass function : a simulation study
Tanuka Chattopadhyay, Tuli De, Bharat Warlu +1
Theoretical and indirect observational evidences suggest that stellar initial mass function (IMF) increases with redshift. On the other hand star formation rates (SFR) may be as hi…
Charged star in (2+1)-dimensional gravity
Ayan Banerjee, Farook Rahaman, Tanuka Chattopadhyay
We obtain a new class of exact solutions for the Einstein-Maxwell system in static spherically symmetric charged star in (2+1)-dimensional gravity. In order to obtain the analytica…
Formation of dwarf ellipticals and dwarf irregular galaxies by interaction of giant galaxies under environmental influence
Tanuka Chattopadhyay, Suma Debsarma, Pradip Karmakar +1
A model is proposed for the formation of gas-rich dwarf irregular galaxies and gas-poor, rotating dwarf elliptical galaxies following the interaction between two giant galaxies as…
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…
