Scientific paper

The data published by Heckman et al. (1980) on a large sample of normal galactic nuclei is used to show that recent detectable star formation has occurred more frequently in the nuclei of barred compared to non-barred disk galaxies. However, the presence or absence of a bar does not enhance the detectability of low-level nuclear activity (anomalous emission lines and/or flat spectrum radio sources).
