ADC_Keywords: Galaxies, IR ; Photometry Mission_Name: ISO Keywords: galaxies: photometry - galaxies: starburst - galaxies: stellar content - infrared: galaxies 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. File Summary:

Note (1): Catalog 1 = Objects with S/N > 4, Probability < 0.02 Catalog 2 = Objects with S/N > 4, P(d,I) > 0.02 Catalog 3 = Objects with S/N > 4, without optical counterpart in IAB Catalog 4 = Objects with 4 > S/N > 3, Probability < 0.02 Catalog 5 = Objects with 4 > S/N > 3, Probability > 0.02 Catalog 6 = Objects with 4 > S/N > 3, without optical counterpart in IAB Note (2): Hammer et al. (1995MNRAS.276.1085H) and Fomalont et al. (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.
