The Properties of High Redshift Galaxies
Abstract
In recent years, a variety of techniques at optical, near-infrared, sub-mm, and radio wavelengths have opened complementary windows on the high-redshift Universe. Here we review the current understanding of the general properties of the z>~2 galaxies detected in the optical (Lyman-break galaxies) and in the sub-mm (SCUBA sources). We list some of the key questions that need to be answered in order to understand the nature and evolution of the high-redshift galaxies. Wherever possible, we present tentative answers given so far to those questions, in particular on the low-redshift couterparts of the high-redshift galaxies, on the impact of dust obscuration on the observed quantities, and on physical characteristics of the high-z systems as inferred from observations.
