In its parallel pointings, NICMOS has given us a unique window on the evolving Universe. We have analyzed the deep parallel NICMOS grism observations, covering more than 60 square arcminutes and down to continuumH1.6=22in the deepest fields. With this slitless grism spectroscopy, NICMOS reveals 33 new line-emitting galaxies. In most cases, the single emission line is likely to be H&agr; at0.7<z<1.9,and their volume density is comparable to that of the brighter galaxies selected by the Lyman break method. Our first Keck LRIS spectrum of one of these galaxies confirms this identification. The inferred star formation rates for the emission-line galaxies are 2–480M./year. We present the details of the grism survey and our analysis so far. ©1999 American Institute of Physics.
