The circumgalactic medium of high-redshift galaxies

Galaxies at High Redshift

Galaxies at High Redshift

Within just the last few years, we have advanced from knowing only a few galaxies at z > 2 to having redshifts for nearly 1000 z ∼ 2–5 objects. The majority of this sample has been detected through the photometric “dropout” technique used so successfully by Steidel and his collaborators. In addition, a handful of objects have already been detected at z > 5, and we may already have a few objects...

The Formation of High-Redshift Submillimetre Galaxies

We describe a model for the formation of z ∼ 2 submillimetre galaxies (SMGs) which simultaneously accounts for both average and bright SMGs while providing a reasonable match to their mean observed spectral energy distributions (SEDs). By coupling hydrodynamic simulations of galaxy mergers with the high-resolution 3D polychromatic radiative transfer code SUNRISE, we find that a mass sequence of...

The Properties of High Redshift Galaxies

0 The Properties of High Redshift Galaxies

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 z2 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 orde...
