Abstract / Description:We present millimeter- and submillimeter-wavelength observations and near-infrared K-band imaging toward the bright gamma-ray burst GRB 010222. Over seven different epochs, a constant source was detected with an average flux density of 3.74+/-0.53 mJy at 350 GHz and 1.05+/-0.22 mJy at 250 GHz, giving a spectral index alpha=3.78+/-0.25 (where F proportional to nu(alpha)). We rule out the possibility that this emission originated from the burst or its afterglow, and we conclude that it is due to a dusty, high-redshift starburst galaxy (SMM J14522+4301). We argue that the host galaxy of GRB 010222 is the most plausible counterpart of SMM J14522+4301, based in part on the centimeter detection of the host at the expected level. The optical/near-IR properties of the host galaxy of GRB 010222 suggest that it is a blue sub-L-* galaxy, similar to other GRB host galaxies. This contrasts with the enormous far- infrared luminosity of this galaxy based on our submillimeter detection (L-Bol approximate to 4x10(12) L-circle dot). We suggest that this GRB host galaxy has a very high star formation rate, SFR approximate to600 M-circle dot yr(-1), most of which is unseen at optical wavelengths.
