 Title: Optical observations and multiband modelling of the afterglow of GRB 041006: Evidence of a hard electron energy spectrum Authors: Misra, KuntalResmi, L.Pandey, S.B.Bhattacharya, D.Sagar, R. Keywords: Gamma-ray burstsGRB afterglowsFlux decaySpectral index Issue Date: 2005 Publisher: The Astronomical Society of India Citation: Bulletin of the Astronomical Society of India, 2005, Vol.33, p487-497 Abstract: We present the CCD Cousins R band photometric observations of the afterglow of GRB 041006. The multiband afterglow evolution is modelled using an underlying `hard' electron energy spectrum with a $p_1 \sim 1.3$. The burst appears to be of very low energy ($E \sim 10^{48}$ ergs) confined to a narrow cone of opening angle $\theta \sim 2.3^{\circ}$. The associated supernova is compared with SN1998bw and is found to be brighter. URI: http://hdl.handle.net/2289/1372 ISSN: 0304-9523 Copyright: (2005) by the Astronomical Society of India.
