4.6. Prospects for the follow-up observations in the future

In order to make detailed submm-wave studies of the astrophysics of high-redshift galaxies, high-resolution images will be required. Existing mm-wave interferometers can provide high-quality images of the brightest submm galaxies (for example Frayer et al., 2000; Gear et al., 2000; Lutz et al., 2001); however, in order to detect rapidly typical LBGs, EROs and hard X-ray sources, the additional sensitivity and resolution that should be provided by ALMA is required. Improved information on the SEDs of dusty galaxies will be obtained using the SIRTF, SOFIA, ASTRO-F and Herschel space- and air-borne observatories: see Tables 1 and 2.
