On QSO Distances and Lifetimes in a Local Model

Abstract

It was previously shown from the redshifts and positions of the compact, high-redshift objects near the Seyfert galaxy NGC 1068 that they appear to have been ejected from the center of the galaxy in at least four similarly structured triplets. Here some of the consequences of assuming such a local model for QSOs are examined. From the ages of the ejection events it is found that in a relatively short time (10 - 100 million years) the intrinsic redshift component in these objects disappears and their luminosity increases to a value close to that of a normal galaxy. This period may then determine the approximate lifetime of a QSO and, in this scenario, QSOs may represent the first, short-lived stage in the life of a galaxy. It is shown that when QSOs are assumed to be "local", their generation rate is found to be constant throughout the age of the Universe. There is no need to invoke an epoch of enhanced, high-luminosity QSO production as is required if their redshifts are assumed to be purely cosmological. Because QSO lifetimes are relatively short (less than 100 million yrs), an initial event (Big Bang) may still be required to explain the high-redshift galaxies whose intrinsic redshift component will have long since disappeared. The Hubble expansion is therefore still expected to apply for normal galaxies.
