NED Abstract

Copyright by Royal Astronomical Society. 1992MNRAS.255..146F The spatial correlation between far-infrared and radio emission in galaxies - I. NGC 6946, M51, NGC 2997 and M83 A. J. Fitt, N. A. Howarth, P. Alexander and A. N. Lasenby Mullard Radio Astronomy Observatory, Cavendish Laboratory, Madingley Road, Cambridge CB3 OHE Accepted 1991 October 3. Received 1991 September 25; in original form 1991 April 16 SUMMARY This paper presents high-resolution far-infrared images of four galaxies using 60-and 100-micron data from the Chopped Photometric Channel instrument of the IRAS satellite. By careful calibration we produce far- infrared colour (temperature) maps, and compare them quantitatively with non-thermal radio images. The far-infrared map for each galaxy shows a broad disc, the colour temperature of which falls with increasing radius, together with discrete sources - the galactic nucleus and warm, far- infrared bright star-forming regions - which provide at least 25 to 35 per cent of the 60-micron flux. The spatial far-infrared-radio correlation is better for warmer dust (traced by 60-micron emission), and its tightness precludes major qualitative differences between star- forming regions within a galaxy. This correlation applies over a larger scale than individual star-forming regions.
