Properties of Emission Line Galaxies at z ≈ 1 to 2

Abstract

A sample of Hα line emitting galaxies at redshifts between 0.7and 1.9 selected from the HST/NICMOS G141 grism parallel survey was recently presented by McCarthy et al. (1999). The galaxies in that sample were identified from quasi-random pointings and therefore should present an unbiased sample of emission line galaxies at that redshift. Spectral as well as morphological properties of the sample derived from the NICMOS images are investigated and compared to those found from HDF galaxies in a similar redshift range and local emission line galaxies.
