Description
Optical R-band imaging data and far-infrared (FIR) Infrared Space
Observatory data from Seyfert galaxies are combined to show that the
compact optical emission from the nuclear and circumnuclear region
correlates reasonably well with the warm FIR emission that is observed
in these objects, while the extended optical emission, which essentially
originates in the host galaxy disk, correlates with the cold FIR
emission that peaks at around 100 mu m. We further show that while the
compact optical emission in all the objects studied always accounts for
less than half of the total R-band emission, the warm FIR emission,
which is attributed to the nuclear and circumnuclear region, dominates
the total FIR luminosity in some objects.
