Scientific paper

We propose to image the field of SN 1998bw to definitively test the association of the supernova with GRB 980425. BeppoSAX X-ray observations of the field have revealed 2 sources (S1, S2) separated by 4.5', each located with 1.5' uncertainty. S1 `coincides' with the SN and exhibits a power-law temporal decay, while S2 is detected (at the BeppoSAX/NFI sensitivity level) to vary around a constant flux value. Chandra ACIS-S observations will enable us (i) to locate S1 and S2 with subarcsec accuracy, (ii) to resolve and determine the flux level and thus the nature of each source and measure their spectrum, and (iii) constrain the energetics of the SN explosion.
