Abstract:
We present evidence that the mid infrared (MIR, rest frame 5-30µm)
is a good tracer of the total infrared luminosity,
L(IR)(=L[8-1000µm]), and star formation rate (SFR), of galaxies up
to z∼1.3. We use deep MIR images from the Infrared Space Observatory
(ISO) and the Spitzer Space Telescope in the Northern field of the
Great Observatories Origins Deep Survey (GOODS-N) together with VLA
radio data to compute three independant estimates of L(IR). The
L(IR,MIR) derived from the observed 15 and/or 24µm flux densities
using a library of template SEDs, and L(IR,radio), derived from the
radio (1.4 and/or 8.5GHz) using the radio-far infrared correlation,
agree with a 1-sigma dispersion of 40%. We use the k-correction as a
tool to probe different parts of the MIR spectral energy distribution
(SED) of galaxies as a function of their redshift and find that on
average distant galaxies present MIR SEDs very similar to local ones.
Description:
The sample consists of 49 IR luminous galaxies detected with ISOCAM
and MIPS, including a subsample of 17 radio-detected galaxies, located
in the Great Observatories Origins Deep Survey in the Northern
hemisphere (GOODS-N) centered on the Hubble Deep Field North (HDFN).
We use three libraries of template SEDs: CE, DH, and LDP (see paper
for details).
