Description

Spectra at 8-13 μm of the nuclei of five nearby bright spiral galaxies are presented. Four of the galaxies, IC342, NGC5195, NGC5236 and NGC253 display prominent spectral structure arising from gas and dust emission. They resemble the spectra of other galaxy nuclei undergoing vigorous nuclear star formation, and it is argued that the strong emission structure arises from the interaction of many HII regions in the central regions of the galaxies. NGC 4736 shows no evidence for emission in the dust and gas features seen in almost all starburst galaxies observed to date. (author)
