A Proposal to Localize Fermi GBM GRBs Through Coordinated Scanning of the GBM Error Circle via Optical Telescopes
T. N. Ukwatta, J. T. Linnemann, K. Tollefson +4
We investigate the feasibility of implementing a system that will coordinate ground-based optical telescopes to cover the Fermi GBM Error Circle (EC). The aim of the system is to l…
Panchromatic observations of the textbook GRB 110205A: constraining physical mechanisms of prompt emission and afterglow
W. Zheng, R. F. Shen, T. Sakamoto +56
We present a comprehensive analysis of a bright, long duration (T90 ~ 257 s) GRB 110205A at redshift z= 2.22. The optical prompt emission was detected by Swift/UVOT, ROTSE-IIIb and…
The Lag-Luminosity Relation in the GRB Source-Frame: An Investigation with Swift BAT Bursts
T. N. Ukwatta, K. S. Dhuga, M. Stamatikos +12
Spectral lag, which is defined as the difference in time of arrival of high and low energy photons, is a common feature in Gamma-ray Bursts (GRBs). Previous investigations have sho…
An unusual stellar death on Christmas Day
C. C. Thöne, A. de Ugarte Postigo, C. L. Fryer +31
Long Gamma-Ray Bursts (GRBs) are the most dramatic examples of massive stellar deaths, usually as- sociated with supernovae (Woosley et al. 2006). They release ultra-relativistic j…
Detection of High-Energy Gamma-Ray Emission during the X-ray flaring activity in GRB100728A
The Fermi Collaboration, L. Piro
We present the simultaneous Swift and Fermi observations of the bright GRB100728A and its afterglow. The early X-ray emission is dominated by a vigorous flaring activity continuing…
