Spatial distribution of 10 micron luminosity in spiral galaxies
Journal Article

· Astrophys. J.; (United States)
The present ground-based 10-micron observations of 133 nearby luminous, noninteracting IR galaxies indicate that about 40 percent of the early-type barred spirals are associated with enhanced 10-micron luminosity in the central (about 1-kpc diameter) region. The luminosity source may be either Seyfert activity or star formation, or both. The difference in bar-central luminosity association in early- and late-type spirals indicates that the bulge/disk ratio may be an important parameter in the determination of central IR luminosity in barred spirals. 34 references.
