Galaxy and AGN counts model
Based on the observed dichotomy in the ages of stellar populations of early-type galaxies on one side (mass-weighted ages of > 8-9 Gyr and formation redshifts z > 1-1.5; named proto-spheroidal galaxies which are progenitors of local massive elliptical galaxies) and late-type galaxies on the other (luminosity-weighted ages of < 7 Gyr and formation redshifts z < 1), we have elaborated a comprehensive ''hybrid'' model to investigate the cosmological evolution of the luminosity function of galaxies and active galactic nuclei (AGNs) in the infrared (IR).
As for proto-spheroids, the physical model proposed by Granato et al. (2004) for the early coevolution of massive proto-spheroidal galaxies and active nuclei at their centers, further elaborated by Lapi et al. (2006, 2011), has been upgraded by working out the epoch-dependent luminosity functions of sources a a whole (stellar plus AGN component), taking into account in a self-consistent way the variation with galactic age of the global SED. Complemented with a phenomenological model for late-type star-forming galaxies (''warm'' starburst and ''cold'' normal spiral) and AGNs (type-1 and type-2) associated with them, this ''hybrid'' model can explain multi-wavelengths, i.e., from mid-IR to (sub-)millimeter, estimates of the luminosity functions at different redshifts, of redshift distributions, of number counts, and of the cosmic infrared background.
These presented contents are based on the new Galaxy and AGN counts model upgraded in ''A hybrid model for the evolution of galaxies and Active Galactic Nuclei in the infrared'' by Cai, Z.-Y., Lapi, A., Xia, J.-Q., De Zotti, G., Negrello, M., Gruppioni, C., Rigby, E., Castex, G., Delabrouille, J. and Danese, L. (2013, ApJ, 768, 21 and my PhD thesis for all the details).
In the following, the adopted SEDs of each component of the model as well as many comparisions between model and observations are presented. Each all.tar.gz link contains all the corresponding tabulated files and figures of each part, while separated file can be found through each corresponding link. The observational data, e.g., LFs or NCs, are also available in IDL save format.
