Scientific paper

For the last two decades, intensive studies have been conducted regarding the continuous emission from quasars and the nuclei of Seyfert 1 galaxies. Observations over at least three frequency octaves are needed for a meaningful analysis of the continuum. Recent satellite observatories have made it possible to obtain the required data. However, some observational problems had to be overcome in connection with the interpretation of the data. One of these problems is related to the observation that the starlight in many Seyfert galaxies is often at least as bright as the nonstellar continuum emitted in their nuclei. In the case of a few Seyfert 1 galaxies, such as Markarian 231, a study of the intrinsic continuum is virtually impossible, because the galaxies are heavily reddened. Questions regarding the accretion disk hypothesis are discussed, and observations which are crucial to an understanding of the accretion process are considered.
