| Abstract: |
Spectroscopic cosmological surveys in the mid- and far-IR with the SAFARI FTS imaging spectrometer
onboard of the future JAXA led SPICA mission will be able to study galaxy evolution directly
separating and quantifying the star formation and black hole accretion processes in galaxies
as a function of redshift.
We show the feasibility of such surveys through simulations
that make use of both observed luminosity
functions and theoretical models for galaxy formation and evolution. The
relations assumed between the line and continuum emission
to trace AGN and star formation activity have been
derived from the observations of local samples of galaxies.
The results indicate that mid-IR and far-IR spectroscopy with the
SAFARI FTS is very efficient to study galaxy evolution from the local
to the distant (z∼3) Universe.
Two different and independent galaxy evolution models predict about
5-8 sources to be spectroscopically detected in three spectral lines in a 2' × 2'
SAFARI field of view, down to the expected sensitivity limit of SAFARI. |
