Abstract / Description of output
We discuss the identification of sources detected by the Infrared Space
Observatory (ISO) at 6.7 and 15 μ in the Hubble Deep Field (HDF)
region. We conservatively associate ISO sources with objects in existing
optical and near-infrared HDF catalogues using the likelihood ratio
method, confirming these results (and, in one case, clarifying them)
with independent visual searches. We find 15 ISO sources to be reliably
associated with bright [I 814(AB) <23] galaxies in the
HDF, and one with an I 814(AB)=19.9 star, while a further 11
are associated with objects in the Hubble Flanking Fields (10 galaxies
and one star). Amongst optically bright HDF galaxies, ISO tends to
detect luminous, star-forming galaxies at fairly high redshift and with
disturbed morphologies, in preference to nearby ellipticals.
