Cirrus models for local and high- z SCUBA galaxies.
EFSTATHIOU A. and ROWAN-ROBINSON M.
Abstract (from CDS):
We also, more controversially, apply this cirrus model to the SEDs of high redshift sources detected in blank-field submillimetre surveys with the Submillimetre Common User Bolometer Array (SCUBA). Surprisingly, an excellent fit is found for many of these sources, with typical values for the optical depth AVand the surface brightness of the stellar radiation field ψ being only a factor of 2-3 higher than for nearby galaxies. This increase is not unreasonable given the expected evolution of dust optical depth in currently favoured star-formation history models.
We conclude that the tendency to interpret the high-z SCUBA galaxies as very highly obscured starbursts may be premature and that these galaxies may be more closely linked to optically selected high redshift galaxies than previously assumed.
