We report results of a deep high-resolution imaging search for the galaxy associated with the damped Lyman-α (DLA) absorber at z=1.859 toward the zem=2.48 quasar QSO 1244+3443, using HST/NICMOS. The observations consisted of NICMOS camera 2 images in the broad filter F160W and the narrow filter F187N. The goal of these observations was to detect redshifted optical continuum and H-α line emission from the DLA absorber. After PSF subtraction, the broad band image shows the possible presence of a compact object at only 0.16" from the quasar center. The PSF-subtracted narrow band image shows no significant emission from any source. These observations of QSO 1244+3443, together with our earlier NICMOS observations of LBQS 1210+1731, suggest that these DLAs have low star formation rates and may be compact objects or low-surface brightness objects with a few knots of continuum emission. This work was supported by NASA grant NAG 5-3042 to the NICMOS Instrument Definition Team.
