Investigating Polarization characteristics of GRB200503A and GRB201009A

Divita Saraogi, Suman Bala, Jitendra Joshi +18

We present results of a comprehensive analysis of the polarization characteristics of GRB 200503A and GRB 201009A observed with the Cadmium Zinc Telluride Imager (CZTI) on board As…

Unified theory of negative and positive spectral lags in GRB prompt phase due to shear Comptonization from a structured jet

Mukesh Kumar Vyas, Asaf Pe'er, Shabnam Iyyani

Positive spectral lags are commonly observed in gamma-ray burst (GRB) prompt phase where soft photons lag behind hard ones in their spectral studies. Opposite to this pattern, a fr…

A detailed time-resolved and energy-resolved spectro-polarimetric study of bright GRBs detected by AstroSat CZTI in its first year of operation

Rahul Gupta, S. B. Pandey, S. Gupta +11

The radiation mechanism underlying the prompt emission remains unresolved and can be resolved using a systematic and uniform time-resolved spectro-polarimetric study. In this paper…

Exploring Gamma-Ray Burst Diversity: Clustering analysis of emission characteristics of Fermi and BATSE detected GRBs

Nishil Mehta, Shabnam Iyyani

Gamma-ray bursts (GRBs) are commonly attributed to the demise of massive stars or the merger of binary compact objects. However, their varied emission characteristics strongly impl…
