Optical Observations of GRB 050401 Afterglow : A case for Double Jet Model
Atish Kamble, Kuntal Misra, D. Bhattacharya +1
The afterglow of GRB 050401 presents several novel and interesting features : [1] An initially faster decay in optical band than in X-rays. [2] A break in the X-ray light curve aft…
GRB 080319B: A Naked-Eye Stellar Blast from the Distant Universe
J. L. Racusin, S. V. Karpov, M. Sokolowski +81
Long duration gamma-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation…
Observations of the Optical Afterglow of GRB 050319 : Wind to ISM transition in view
Atish Kamble, L. Resmi, Kuntal Misra
The collapse of a massive star is believed to be the most probable progenitor of a long GRB. Such a star is expected to modify its environment by stellar wind. The effect of such a…
The dark nature of GRB 051022 and its host galaxy
A. J. Castro-Tirado, M. Bremer, S. McBreen +17
We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 hours and ~1.15 yr after the event. It is the most intense gamma-ray burs…
GRB 030329: three years of radio afterglow monitoring
A. J. van der Horst, A. Kamble, R. A. M. J. Wijers +7
Radio observations of gamma-ray burst (GRB) afterglows are essential for our understanding of the physics of relativistic blast waves, as they enable us to follow the evolution of…
