NED Abstract

Copyright by Royal Astronomical Society. 1995MNRAS.276.1373S Parsec-scale radio cores in spiral galaxies Elaine M. Sadler, O. B. Slee, J. E. Reynolds and A.L. Roy School of Physics, University of Sydney, NSW2006, Australia Australia Telescope National Facility, CSIRO, PO Box 76, Epping, NSW2121, Australia Accepted 1995 May 19. Received 1995 May 18; in original form 1995 March 6 ABSTRACT We have used the Parkes-Tidbinbilla Interferometer to search for compact (<0.03 arcsec) radio continuum cores in 54 nearby spiral galaxies, 22 of which have Seyfert nuclei. In contrast to the radio cores of elliptical galaxies, the few parsec- scale cores seen in spirals usually have steep radio spectra, with an apparent median spectral index of -1.0. At present, it is not clear whether this is because the radio cores of spiral galaxies are larger than those in ellipticals (and so are partly resolved by the interferometer), or whether the core spectra of ellipticals and spirals are intrinsically different. Key words: galaxies: active - galaxies: nuclei - galaxies: Seyfert - galaxies: spiral - radio continuum: galaxies.
