  In this paper I discuss the issue of the so-called 25 micron-peakers, which
were discovered with IRAS, and consist almost solely of broad-line radio
galaxies. I find that this peak is caused by the absence of colder dust that
emits at 60 micron and not by an excess of hot dust, as suggested by the name.
On optical images, the 25 micron-peakers show a lack of extended dust. The
peakers are consistent with being in a later evolutionary stage, in which all
the extended dust has been formed into stars and the dust torus is smaller. If
the 60 micron dust is heated by stars, there might be a correlation between the
star-formation rate and the power of the AGN.
