Abstract:
Optical and infrared monitoring of the afterglow site of gamma-ray
burst GRB 031203 has revealed a brightening source embedded in the
host galaxy, which we attribute to the presence of a supernova (SN)
related to the GRB ("SN 2003lw"). We present details of the discovery
and evolution of SN 2003lw from 0.2 to 92 days after the GRB, derived
from SMARTS consortium photometry in I and J bands. GRB 031203 was an
intrinsically faint GRB, and the optical light curve is dominated by
the SN after the first few days. A template Type Ic light curve,
constructed from SN 1998bw photometry, is consistent with the peak
brightness of SN 2003lw, although the light curves are not identical.
Differential astrometry reveals that the SN, and hence the GRB,
occurred less than 300h71-1pc (3sigma) from the apparent galaxy
center.
Description:
Observations commenced on 2003 December 4 at 3:00 UT, approximately 5
hrs after the INTEGRAL detection of the long-duration (20s) GRB
031203, and follow-up imaging continued for the next 3 months. Data
were obtained using the ANDICAM (A Novel Dual Imaging CAMera)
instrument mounted on the 1.3m telescope at Cerro Tololo
Inter-American Observatory.
