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…
Further evidence for intra-night optical variability of radio-quiet quasars
A. Goyal, Gopal-Krishna, Ram Sagar +2
Although well established for BL Lac objects and radio-loud quasars, the occurrence of intra-night optical variability (INOV) in radio-quiet quasars is still debated, primarily sin…
Early optical and millimeter observations of GRB 030226 afterglow
S. B. Pandey, R. Sagar, G. C. Anupama +4
The CCD magnitudes in Johnson and Cousins photometric passbands for the afterglow of the long duration GRB 030226 are presented. Upper limits of a few mJy to millimeter…
SN 2002ap, the hypernova of class Ic
S. B. Pandey, D. K. Sahu, G. C. Anupama +2
The supernova SN 2002ap was discovered in the outer regions of the nearby spiral M74 on January 29.4 UT. Early photometric and spectroscopic observations indicate the supernova bel…
A flattening in the Optical Light Curve of SN 2002ap
S. B. Pandey, G. C. Anupama, R. Sagar +3
We present the broad band optical photometry of the Type Ic supernova SN 2002ap obtained during 2002 February 06 -- March 23 in the early decline phases and also later…
Optical Photometry of the GRB 010222 Afterglow
R. Cowsik, T. P. Prabhu, G. C. Anupama +5
The optical afterglow of GRB 010222 was observed using the recently installed 2-m telescope at the Indian Astronomical Observatory, Hanle, and the telescopes at the Vainu Bappu Obs…
