Abstract:
The Canada-France Redshift Survey 1452+52 field has been deeply imaged
with the Infrared Space Observatory using ISOCAM through the LW3
filter (1218 µm). Careful data analysis and comparison with deep
optical and radio data have allowed us to generate a catalog of 78
15 µm sources with both radio and optical identifications. They are
redder and lie at higher redshift than I-band-selected galaxies, with
most of them being star-forming galaxies. We have considered the
galaxies detected at radio and 15 µm wavelengths, which potentially
include all strong and heavily extincted starbursts, up to z=1.
Spectral energy distributions (SEDs) for each of the sources have been
derived using deep radio, mid-IR, near-IR, optical, and UV photometry.
The sources were then spectrally classified by comparing with SEDs of
well-known nearby galaxies. By deriving their far-IR luminosities by
interpolation, we can estimate their star formation rate (SFR) in a
way that does not depend sensitively on the extinction.

(1991AJ....102.1258F 1991AJ....102.1258F) comment that the fainter source (IAB ∼ 23.9)
galaxy, which is 2'' away, should be the optical counterpart.
Unfortunately, no spectrum of the fainter galaxy is available.
