The effect of AGN on host-galaxy dust heating

Theorists have recently started to examine the effects of AGN radiation on dust heating on host galaxy scales via performing dust radiative transfer on simulated AGN-hosting galaxies. We and others have found that in some cases, obscured AGN heating can dominate the galaxy-scale cold dust emission, even at rest-frame wavelengths >100 micron. I will summarize these results and discuss implications for using FIR emission as a star formation rate tracer.
