Observations of the Hubble Deep Field with the Infrared Space Observatory V. Spectral energy distributions starburst models and star formation history

摘要: We have modelled the spectral energy distributions of 13 Hubble Deep Field (HDF) galaxies reliably detected by Infrared Space Observatoiy (ISO). For two emission ISO is consistent with being starlight or infrared 'cirrus' in galaxies. remaining 11 there a clear mid-infrared excess, which we interpret as from dust associated strong starburst. 10 these are spirals interacting pairs, while one an elliptical prominent nucleus and broad lines. give new discussion how star formation rate can be deduced far-infrared luminosity, derive rates for 8-1000o M? yr-1, where o takes account uncertainty initial mass function. The HDF clearly forming stars at prodigious compared nearby normal discuss implications our detections history heavy element Universe. Although uncertainties calibration, reliability source detection, associations starburst models remain, it that plays important role out to redshift 1 least.
