Imaging polarimetry of Comet C/2012 L2 (LINEAR)
P. DebRoy, H. S. Das, Biman J. Medhi
We present the polarimetric results and analysis of comet C/2012 L2 (LINEAR) observed at 31.1 phase angle before perihelion passage. The observations of the comet were carr…
Trajectory of a light ray in Kerr field: A material medium approach
Saswati Roy, A. K. Sen
The deflection of light ray as it passes around a gravitational mass can be calculated by different methods. Such calculations are generally done by using the null geodesics under…
Light defection due to a charged, rotating body
Sarani Chakraborty, A. K. Sen
According to GTR and subsequent developments in the field, it is known that there are three factors namely mass, rotation and charge that can influence the space-time geometry. Acc…
A note on Low Energy Effective Theory of Chromo Natural Inflation in the light of BICEP2 results
Anindita Bhattacharjee, Atri Deshamukhya, Sudhakar Panda
Recent result of BICEP2, revealing a larger value of tensor to scalar ratio (r), has opened up new investigations of the in ationary models to fit the experimental data. The experi…
Java application for the superposition T-matrix code to study the optical properties of cosmic dust aggregates
P. Halder, A. Chakraborty, P. Deb Roy +1
In this paper, we report the development of a java application for the Superposition T-matrix code, JaSTA (Java Superposition T-matrix App), to study the light scattering propertie…
Study of background star polarization and polarization efficiency of three selected Bok globules CB56, CB60 and CB69
A. Chakraborty, H. S. Das, D. Paul
We present the polarization maps of three selected Bok globules CB56, CB60 and CB69 constructed using a V-band data from a CCD imaging polarimeter. The aim of this work is to measu…
