Scientific paper

It is found that the central, optically bright region of the spiral galaxy NGC 1097 is a strong 10 micron source. A striking correlation is seen between the optical and infrared surface brightnesses. The properties of these sources imply that young stars power the infrared emission. It is inferred that the central 30 arcsec of NGC 1097 has a large bolometric luminosity of about 10 to the 11th solar luminosities, most of which originates in a ring approximately 2 kpc in diameter. These observations strongly support the hypothesis that the infrared emission from galaxies is often associated with bursts of star formation.
