Abstract
We present the results from the spectroscopic identifications of the ELAIS sources in the southern fields S1 and S2. Two main extragalactic classes have been found: z < 0.5 star-forming galaxies (similar to75%), and AGN (similar to25%). similar to20% are dust enshrouded starburst galaxies [e(a) spectral. All the galaxies appear more dust extincted in the optical than nearby normal galaxies. The evolution of galaxies is fitted by a strong evolution for only a fraction of the whole population. AGN1 evolves according to a pure luminosity evolution, while no evolution is found for the AGN2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
