Need for “Complicated” Models? Mass to light ratio Total group  luminosity Variation of M/L with total group luminosity shows how  the efficiency of galaxy  formation should depend on  halo mass.  Galaxy  formation most  efficient Effectiveness of feedback  processes and variation in  gas cooling time within haloes  of different mass drive change in M/L Eke et al. 2004, 2005 Creation of the Far-IR Populations SPICA Workshop, November 2006
The Challenge of (sub-)mm Galaxies Creation of the Far-IR Populations SPICA Workshop, November 2006
The Challenge of (sub-)mm Galaxies SCUBA image of HDF  More star formation at high-z? Creation of the Far-IR Populations SPICA Workshop, November 2006
The Challenge of (sub-)mm Galaxies *Population of sources missed by Lyman-break dropout & UV imaging *Possibly more star formation at high redshift than previously thought *Inferred SFRs huge ~ 1000 Msun/yr!  *Is all emission due to starburst or is some from an AGN? *Is a SCUBA source an elliptical galaxy in formation?  *Massive galaxies in place at high-z? How can SCUBA sources be accommodated in  hierarchical models? Creation of the Far-IR Populations SPICA Workshop, November 2006
Modeling Dust Extinction & Emission *Naïve model:  assume dust temperature  *Physically inconsistent! *Dust temperature should be determined by thermal equilibrium between  heating and cooling of grains *With the bolometric luminosity and dust mass as parameters, and  with the  dust in thermal equilibrium,  Which gives : Creation of the Far-IR Populations SPICA Workshop, November 2006

  • 11. The Challenge of (sub-)mm Galaxies *Population of sources missed by Lyman-break dropout & UV imaging *Possibly more star formation at high redshift than previously thought *Inferred SFRs huge ~ 1000 Msun/yr! *Is all emission due to starburst or is some from an AGN? *Is a SCUBA source an elliptical galaxy in formation? *Massive galaxies in place at high-z? How can SCUBA sources be accommodated in hierarchical models? Creation of the Far-IR Populations SPICA Workshop, November 2006
  • 12. Modeling Dust Extinction & Emission *Naïve model: assume dust temperature *Physically inconsistent! *Dust temperature should be determined by thermal equilibrium between heating and cooling of grains *With the bolometric luminosity and dust mass as parameters, and with the dust in thermal equilibrium, Which gives : Creation of the Far-IR Populations SPICA Workshop, November 2006
