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…
The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125
Adria C. Updike, Joshua B. Haislip, Melissa C. Nysewander +52
We report on multi-wavelength observations, ranging from the X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the prese…
Photometric and Spectroscopic study of a highly reddened type Ia supernova SN 2003hx in NGC 2076
Kuntal Misra, D. K. Sahu, G. C. Anupama +1
We present CCD photometry and optical spectra of the type Ia supernova SN 2003hx which appeared in the galaxy NGC 2076, obtained till 146 days after the epoch of …
Multiwavelength analysis of the intriguing GRB 061126: the reverse shock scenario and magnetization
A. Gomboc, S. Kobayashi, C. Guidorzi +30
We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multi-color optical imaging from ten ground-based telescopes. G…
