Abstract:
We present deep optical photometry of the afterglow of gamma-ray burst
(GRB) 041006 and its associated hypernova obtained over 65 days after
detection (55 R-band epochs on 10 different nights). Our early data
(t<4days) joined with published GCN data indicate a steepening decay,
approaching Fν{prop. to}t-0.6 at early times (t≪1day) and
Fν∝t-1.3 at late times.
Description:
The majority of our data were obtained with the MegaCam CCD mosaic
mounted on the MMT 6.5m telescope. Additional data were obtained using
the 1.8m Vatican Advanced Technology Telescope, the Magellan 6.5m
Baade and Clay telescopes, and the Keck II 10m telescope.
