  • The “standard model” of AGN involves a supermassive black hole accreting gas, possibly through a flattened disk. This model enjoys widespread popularity among astronomers, but convincing proof has been elusive. Recent observations of “dormant” black holes in nearby galactic nuclei encourage the idea that black holes lie at the centers of AGN. An understanding of the nature of the accretion flow seems most likely to come from Doppler shifts of spectral features. The thermal continuum from the inner disk offers an intriguing opportunity. Theoreticians should not neglect the study of the thin disks that should exist for some AGN parameters, as these relatively “tame” objects may yield the most reliable observational tests. The broad emission lines may represent the debris of tidally disrupted stars.
