Description
Middle and far infrared studies of the irregular galaxy M 82 and of
Seyfert galaxies are presented. M 82 was observed spectrophotometrically
from 8 to 13 microns at 6 different positions selected across its 10
microns emitting region. A model is proposed which explains
satisfactorily most of the observed properties of M 82 from X-ray to
radio wavelengths. It is also suggested that a similar model may be
applied to other active nuclei, like the emission line alaxy NGC 1614
and the classical Seyfert 1 galaxy NGC 7469. The far IR emission from
Seyfert galaxies was also studied. Data analyzed are drawn from the
recently released IRAS catalog. Seyfert galaxies are strong far infrared
sources, but unlike the near and mid IR emission from these sources, the
far IR emission does not appear to be produced by the active nucleus.
Seyfert galaxies are depicted as composed of an active nucleus that
powers the near and mid IR, plus a galactic envelope that supports the
starburst episodes.
