The nature of near-infrared emission from spiral galaxies.

JAMES P.A. and SEIGAR M.S.

Abstract (from CDS):

We present K-band spectroscopy for several regions of three nearby spiral galaxies, NGC 613, NGC 628 and NGC 7741. Analysis of the depth of the 2.293µm CO absorption feature in these spectra reveals that some regions have deep absorptions, indicative of recent star formation, while others have anomalously shallow absorptions. We interpret the latter as evidence for a significant but localised contribution to the 2.3µm light from hot dust with an effective temperature of ∼1000K, which could have a significant effect on the K-band morphologies of star-forming galaxies.
