摘要

Using the Suprime-Cam on the Subaru telescope, we carried out deep multi band (V, R, I, z′) imaging for the host galaxy of GRB980329, which is one of well studied "optically dark" gamma-ray bursts. The host galaxy was detected clearly in all bands. Combining these measurements with published near-infrared data, we determined the photometric redshift of the galaxy as z = 3.56 (3.21-3.79 at 90 range). The implied V-band extinction is rather low, typically ∼ 1 mag. At z = 3.56, the isotropic 40-700 keV total energy of GRB980329 is calculated as (2.1 ± 0.4) × 10⁵⁴ erg. Assuming that this GRB was emitted by a pair of jets with a total energy of 10⁵¹ ergs, their opening angle is calculated as θ_j = 2.1. The present results disfavor the high-redshift hypothesis and the high extinction scenario of optically dark bursts.
