Revealing characteristics of dark GRB 150309A: dust extinguished or high-z?

A. J. Castro-Tirado, Rahul Gupta, S. B. Pandey +28

Dark GRBs constitute a significant fraction of the GRB population. In this paper, we present the multiwavelength analysis of an intense two-episodic GRB 150309A observed early on t…
