With reasonable assumptions, however, we can make predictions for the source populations that we should detect in the AXAF and XMM deep surveys.

Optical and near-infrared (NIR) deep surveys have been very powerful for detecting very faint sources in the high-redshift (z) universe.

In the near- and mid-infrared regions, wide and deep surveys of pre-selected sky areas will be made with large low-noise arrays.
